The 5 Best-Selling Handguns of 2016

2016 looks like it will be a record year for gun sales. The number of NICS background checks forfirearm purchases has risen annually for 18 straight months, hitting 22.2 million at the end of October versus 23.1 million in 2015.

Analysts expect Smith & Wesson (NASDAQ: SWHC) and Sturm Ruger (NYSE: RGR)-- the only two publicly traded gunmakers in the U.S. -- to respectively grow their revenues by26% and 13% thisyear. Let's takea look back at the five top selling handguns of the year, as listed by Gunbroker.com, and what they tell us about today's American firearm market.

1. Smith & Wesson M&P Shield

The Smith & Wesson M&P Shield, which was introduced in 2005, is a lightweight, concealable pistol which is encased in a polymer frame. The Shield comes in 9mm, 40 S&W, and .45 full auto calibers, and is widely used by law enforcement and military personnel. The Shield is often praised forits slim profile, ergonomics, ease of use, and overall accuracy. As a striker-fired pistol, it lacks a protruding hammer in the back, making it easier to conceal and carry.

The M&P (military and police) brand hasbecome Smith & Wesson's flagship brand over the past decade. That family now includes the M&P Shield, M&P 15 Auto, various other variants, and even branded M&P knives. During last quarter's conference call, CEO James Debney acknowledged that the "halo" effect of the M&P brand gave its products more credibility as they were "used, adopted, and well-regarded by the professional community."

2. Ruger LCP

The Ruger LCP (lightweight compact pistol) is a .380 automatic pocket pistol. The tiny 9.4 oz. pistol, which was introduced in 2008, was Ruger's first ultra-light defensive pistol designed for civilians' concealed carry needs.

The pistol has a glass-filled nylon frame, and uses a "single-strike double-action" mechanism which acts similarly as a striker-fired pistol. Ruger recently upgraded theLCP with the LCP II, which adds improved sights, a larger grip surface for distribution of recoil, and a shorter, crisper single-action trigger with an inner trigger safety.

3. Springfield XD-S

Springfield Armory's Springfield XD-S, which was launched in 2012, is very similar to Smith & Wesson's M&P Shield. Both pistols are encased in polymer frames and are striker-fired. However, the XD-S only comes in 9mm and .45 ACP calibers.

Whereas the M&P Shield was developed in the United States, the XD (extreme duty) line of semi-automatic pistols actually originates in Croatia, where they were branded as HS2000 pistols for military use. XD pistols have also been approved for a wide range of law enforcement agencies across theUnited States.

4. SIG Sauer P938

SIG Sauer's P938, which also arrived in 2012, is a subcompact single-action 9mm pistol. Unlike most other subcompact 9mm handguns, the P938 has an all-metal frame of anodized aluminum alloy and stainless steel. Unlike the three aforementioned pistols, the P938 is hammer-fired -- but it's still lighter than the M&P Shield and the Springfield XD-S.

Specialty versions of the P938 include the Blackwood, Rubber Grip, Extreme, Nightmare, Rosewood, AG, Equinox, andSAS -- which all tweak the finish with a more premium appearance. As a result, the P938 is priced as a "luxury" firearm, with specialty models priced between $600 and $800.

5. Glock 19

The 9mm Glock 19 was introduced in 2010 as a reduced-size version of the Glock 17. Like the M&P Shield and XD-S, the Glock 19 is a polymer-framed, striker-fired pistol. It's widely issued as a service pistol among private and public security agencies, and its small size makes it a popular concealed carry or backup weapon.

The key takeaways

The popularity of these five handguns indicates that smaller concealed carry weapons will likely remain more popular than larger pistols. With the Republicans now in control of the presidency and congress, investors and gun owners might assume that gun sales will rise over the next four years.

However, gun sales tend to surge with the threat of tighter gun controls, which would more likely occur under a Democrat administration. As a result, analysts expect Smith & Wesson's sales to rise just 1% next year and Ruger's sales to fall 14%. Therefore, these five guns will likely stay popular, but year-over-year comparisons might look weak over the next few years.
