Harvard Study: Gun Control Is Counterproductive

The study, which just appeared in Volume 30, Number 2 of the Harvard Journal of Law & Public Policy (pp. 649-694), set out to answer the question in its title: "Would Banning Firearms Reduce Murder and Suicide? A Review of International and Some Domestic Evidence." Contrary to conventional wisdom, and the sniffs of our more sophisticated and generally anti-gun counterparts across the pond, the answer is "no." And not just no, as in there is no correlation between gun ownership and violent crime, but an emphatic no, showing a negative correlation: as gun ownership increases, murder and suicide decreases.

Engineering is Crucial Element of Burgeoning Firearms Industry

by Kelly Koltun

Firearm sales have increased exponentially over the past few years, and forecasts are continuing to escalate, reflecting an increase in the popularity of hunting, a rise in the desire for personal protection, and a variety of other socio-economic factors. As manufacturers seek to meet demand while decreasing costs, reducing weight, and increasing durability, the spotlight is turning to engineering and design capabilities in the industry. Engineered metal solutions, including expertise in such technologies as precision CNC machining, metal injection molding (MIM), laser welding, and stamping, are key to meeting the challenges of this booming industry.

Demand is fueling boom
In 2011 and 2012, firearms had strong, record-setting sales. According to the National Shooting Sports Foundation (NSSF), there have been 24 straight monthly increases in the number of the National Instant Criminal Background Check System (NICS) background checks, when compared to the same period of the previous year. The FBI checks are required by all licensed firearms dealers to ensure that a customer does not have a criminal record or isn’t otherwise ineligible to make a purchase. [1] The NICS statistics are not actual sales data, but since one cannot purchase a firearm without getting one, it is likely that most people getting a NICS check are buying a firearm.
Check the history of NICS checks, as adjusted by NSSF. There were 840,412 checks in May 2012, an increase of 20.6 percent over the NSSF-adjusted NICS figure of 696,947 in May 2011. For comparison, the unadjusted May 2012 NICS figure of 1,305,392 reflects a 7 percent increase from the unadjusted NICS figure of 1,219,872 in May 2011.
In addition to background-check statistics, the NSSF notes that firearms production and importation, firearm-retailer surveys and on-the-ground reports from retailers nationwide reveal that interest in firearm ownership is high.
In fact, the increased demand has had major firearms manufacturers struggling to keep up, with some even having to stop taking orders. For example, Sturm, Ruger & Co. resumed taking new orders from its independent wholesale distributors in late May 2012, after temporarily suspending the acceptance of new orders in March. [3] Ruger had received orders for more than one million firearms in the first quarter; the company said its production and shipments in the first quarter of 2012 increased more than 50 percent from the first quarter of 2011.
What’s fueling the boom? Experts cite several reasons for the increase, including uncertainty in a presidential election year, warriors returning from the battlefields, the comeback of the hunter, and economic uncertainty. [1] Personal defense is also seen as a large and growing trend, resulting in a marked increase in compact pistols.

Expanding engineering to accommodate the boom in the firearms market
Engineering firms are rapidly expanding to provide the engineering and design capabilities necessary to accommodate the boom in the firearms market. In guns and other projectiles, most branches of mechanical engineering are applied, including wear-properties (tribology) of the moving parts, manufacturing of highly precise machining processes, and system design. A high degree of design collaboration with top gun manufacturers is imperative to meet the needs of today’s firearms purchasers, whether they are for personal protection, hunting, or for the military.
For example, Tracy MacNeal, ATW Company’s director of business development, notes the importance of engineering expertise for helping firearms manufacturers hit tight tolerances, and resolve complex issues. “Identifying prototyping needs, turning around a prototype quickly, developing the best materials for the application, and providing advice on appropriate designs and tolerances, are services that are essential to supporting today’s firearms industry,” says MacNeal. Warwick, RI-based ATW Companies is a provider of highly engineered metal solutions to the metal component marketplace.
According to Chris Schirmer, quality control manager at STI International, a Texas-based company that manufactures complete M1911 pistols and parts for competition, duty and self-defense, designers must pay careful attention to the application of the firearm. He asks, “What is the intent of the firearm – Is it concealed carry, competition, or law enforcement? Each area of firearm use will have specific requirements that need to be met, which requires decisions on size, material, weight, length, and caliber.”
Since most people have very limited budgets, consumers like to buy inexpensive firearms, and most manufacturers are responding by looking for ways to reduce costs. This is why many firearm manufacturers are using molded plastics, aluminum extrusions, and die cast zinc parts in their new designs. All of these processes can be used to make inexpensive, strong, and durable components.
High tolerances and precision function is key to every component in gun manufacturing. For example, Metalform Magazines, a division of A.T. Wall, produces firearms magazines, a relatively simple device that feeds the rounds into the pistol’s chamber via a spring-loaded follower mechanism. Although standard magazines tend to cost only $15-75 depending on design/size, this small component can determine how well a $2000 pistol works.
Kevin Collins, a senior design engineer at Savage Arms, a Westfield, Massachusetts-based manufacturer of rifles and shotguns, explains that designing weapons for today’s firearms purchasers depends not only on precision, but also weight. “Lighter and stronger has been a goal for a long time, and the design mantra has been to look to polymers, aluminum, titanium, and carbon fiber to get just the right combination of durability and weight.” He notes that today’s hunters are looking for lightweight rifles, and designers are responding to the demand by looking at aluminum frames and receivers. This can save as much as 30 to 50 percent of the weight of the firearm and shipping of the raw material, and also saves on machining costs.
The application of the firearms determines much of the desired weight requirements. Collins notes that in hunting applications, in which the hunter might be making only a few shots in a given day, a lighter gun is easier to carry and the extra recoil is not much of a problem. By contrast, in a shooting range application, in which the shooter might be firing many rounds, the recoil associated with a very lightweight rifle will cause fatigue fairly quickly. Engineering design seeks to resolve these polarized requirements.
Reinforced plastic with steel ribbing is another design innovation being pursued, though Collins acknowledged the downside of polymers, especially where the weapon may be used in areas with a large temperature fluctuation, as steel components may expand when plastic does not. The variation in these temperature coefficients will eventually cause loosening of the gun’s components, which is not desirable.

Metal injection molding for firearms manufacturing
Metal injection molding (MIM) is a popular choice for relatively high precision at a low cost. MIM combines powder metal with a low melt polymer to create a feedstock that is molded using conventional injection molding equipment and molds. After molding, the plastic, which is known as the binder, must be removed in a step called debinding. After debinding, the parts are placed into high temperature sintering furnaces and sintered. The result is a solid metal part created from powder metal to near net shape at 96 percent density of wrought metal.
There is little waste in the MIM process compared to other competing technologies, making MIM a green technology. MIM is a low cost, high volume manufacturing process that produces geometrically complex metal parts that are difficult or near impossible to produce using other conventional metal fabrication technologies. This means MIM can be used to produce complex shapes that can cost 20 to 50 percent of a machined part, producing far less material waste, with high production rates.
Key major firearms manufacturers have adopted MIM widely, and new projects are likely to include MIM parts, due to the cost and consistency of the process. Depending on volume requirements and part complexity, MIM can significantly reduce the component cost and in some instances yield parts that could not be made using any other method. Manufacturing of metal components using MIM technology has enabled U.S. companies to stay within the U.S. for sourcing components, due to MIM’s high manufacturing capability and competitive pricing.
John Lewinski, director of supplier management at Springfield, MA-based Smith & Wesson, notes that any of the company’s new projects are likely to include MIM parts, due to the cost and consistency of the process. “MIM has allowed us to take cost out of the product while maintaining quality and therefore pass the savings on to the consumer,” says Lewinski.
Collins agrees, calling MIM the modern replacement to investment casting, especially for small parts. He says that MIM is a fairly new technology that is being used more and more for making firearm components. The parts are dimensionally consistent, fairly inexpensive, and the surface finish is smoother than machined or investment cast (IC) components. To save on costs, especially for entry level guns, designers are looking to save on costs by designing guns with less than smooth mirror finish on mating parts, or where parts are not super close fitting, but which are utilitarian and result in a perfectly functional firearm.
In his view, the main drawback of current MIM technology is the material designation and selection. Most engineers are not familiar with the materials used for MIM parts. He explains, “Most MIM parts are not made from common AISI materials such as 4340 and 8620 alloy steels, and this is certainly a drawback for anyone wanting to make parts for existing military rifles such as the M14 and M16.” According to Collins, the rifles purchased by the U.S. military use lots of parts made from AISI 8620 alloy steel, and they don’t have options for similar or equivalent materials. “Getting new materials approved for military use can be a hassle.”
Also, he notes that at this point, IC still has a distinct advantage over MIM in that the cast parts can be bigger or heavier than the MIM parts. Next to stocks and barrels, receivers are the largest and most complex components for firearms. “Making a receiver with the MIM process would be a good test to validate the strength and durability of MIM components and materials,” said Collins.
Basically, Collins believes that creative designs and manufacturing methods will be key, similar to the way firearm manufacturers during WWII found the most economical and least time consuming ways of manufacturing firearms. In his view, there is no reason to make a firearm component any stronger or more complicated than it needs to be. This would drive up its manufacturing cost, but it wouldn’t necessarily improve its quality.
Chris Schirmer of STI International, also believes that that the introduction of MIM components to the firearms industry has had a significant impact. “MIM allowed the manufacturers to create a ready to use, high detail metal part in high volume at low cost,” said Schirmer. “Unfortunately the early MIM process left a lot to be desired and the manufacturers using these parts experienced failures.” Schirmer explains that, over time, the process has improved to the point that it is a perfectly acceptable method of manufacture for most manufacturers, including STI. He does acknowledge that there is still concern in the public about the early failures and its use may never be accepted by some consumers or 100 percent by manufacturers.
According to ATW’s Tracy MacNeal, designers must also pay careful attention to the identification and management of complex secondary operations that are performed on the MIM part, which may include laser marking, sub-assemblies, post machining operations, and coating and plating requirements. Tooling design expertise and use of the latest analytical tools, for example SolidWorks and MoldFlow software, are the final piece of the design puzzle. Companies with consolidated and broad capabilities are often a good solution for firearms manufacturers seeking to meet demand in today’s boom, while ensuring the best balance of design and production are satisfying the market.

Publicity Is Not A Promise

Publicity Is Not A Promise
 by John M. Buol Jr.

The notion of an “anti-gun media” is a lie. Outside of a small group of reporters, journalists and editors that let their personal opinions over step their impartiality, most media people, like most Americans, don't have a strong enough opinion to do anything about the issue one way or another. There is no grand cabal of media magnates plotting the downfall of the gun industry in hidden, smoke-filled rooms.

The “anti-gun media” is an invention of pro-gun lobbyists used as an excuse for why shooting sports fail to make mainstream media and, sometimes, as a boogeyman to scare people into giving money to political and lobby group fundraisers. Garnering publicity and earning media coverage is a long row to hoe for every organization.

Outside your circle of colleagues, friends and other like-minded folks, nobody cares about your interest in firearms and shooting. Trying to convince an editor or publisher in print, broadcast or online media to pay attention requires hosting an on-going series of regular, interesting events and continuous promotion. It is a process of years with no guarantee of success. No gun or hunting organization today is doing this effectively which is the main reason why pro gun publicity is so sparse.

Looking at the NRA's own numbers, only two percent of the membership participate in NRA sanctioned or registered events. If 98% of card-carrying NRA members ignore NRA shooting events, why should we expect anyone in the media to care about them?

“Oh, but we can’t blame ourselves! It’s not our fault that we fail to host interesting events and consistently promote them. No, we’re victims of the “anti-gun media” that have a liberal agenda to censor us.” Hogwash!

Take off your tin foil hat, Sparky. This is a problem for everyone. Check out this story:

Rotary District 5840 ( here in Texas held a fundraiser billed as the “Million Dollar Dinner.” They exceeded their goal and raised $1,070,000 for the Rotary Foundation Permanent Fund, which is used for literacy programs and Polio eradication. Chairman of the District Rotary Foundation Committee Doug Whinnery and 5840 District Governor Sherri Muniz presented a $1.07 Million check to Rotary International President Kalyan Banerjee at the District’s Million Dollar Dinner in San Antonio. The money raised goes to the Permanent Fund of the Rotary Foundation, ensuring the work of the Foundation can continue in the future.

A week later at a Rotary meeting one of the event organizers mentioned having problems with uncooperative local reporters to cover the event. He noted it was hard to get coverage during sweeps for something not directly impacting the local community.

They raised and gave away over $1 Million and still couldn’t land a story. When was the last time your shooting club or gun shop raised and gave away a million bucks? So, following the rhetoric of pro-gun lobby groups, the media must also be “anti-Rotary” and “anti-charity.” Or, maybe, publicity is not a promise. It is a long, imperfect effort fraught with difficulties. No single event can be expected to catch everyone’s attention.

The Honorable Renee McElhaney 73rd District Court Bexar County Courthouse 100 Dolorosa, 2nd floor San Antonio, TX 78205 Dear Judge McElhaney, Your decision concerning the A Place to Shoot gun range is suspect and needs to be reconsidered. The Municipal Golf Association - San Antonio (MGA-SA) is funded by the city and has board members appointed by the city. By your decision, this city-funded organization is now conveniently not associated with the city as it suits them in this matter. If this is the case, and MGA-SA wishes to no longer be an entity of the city, all city funding for them should immediately cease and they be ordered to pay back all received funds with interest. Marksmanship competition is the only sport required by Federal Law (the National Matches are conducted in accordance with Title 36, U. S. Code, § 40725-40727) and any government funding for sport should be directed there. Police Chief William McManus has said an in-depth investigation could not determine the bullet's origin and said there was no way to tell if it came from the range. As a small arms instructor with the US Army I know the chances of any claimed errant bullets originating from the A Place to Shoot rifle range is infinitesimal. We have a city-funded organization illegally suing a shooting range over an incident that likely wasn't the fault of the range. I respectfully request that you reconsider your decision. Respectfully, John M. Buol Jr.
