Smith & Wesson didn’t just dip its toes into the .308 Winchester AR market—it jumped in head first with its M&P10.

Thanks to its XD-S in .45 ACP, Springfield Armory was one of the hottest companies of 2012. The XD-S was so innovative that it went on to be named the American Rifleman Handgun of the Year. When you knock one out of the park like that, there's not a lot that needs changing, and Springfield agreed. So, for 2013, Springfield has rolled out a slightly updated version of the XD-S: except this time it's in 9 mm.

There are plenty of pocket pistols on the market today, but few can compete with the North American Arms Black Widow in size and portability. This five-shot, single-action, mini-revolver is only about 5¾-inches long, and although its frame and cylinder are made of stainless steel, the gun weighs less than 9 ounces.

TriStar Sporting Arms introduced its pistol line in 2012, and has expanded it for 2013. One of its premier new offerings is the C-100, which is manufactured in and imported from Turkey.

The name A-15 refers to DPMS' .223/5.56 caliber, gas-driven rifles. But within that family you can find a number of different models and configurations—including the latest Gun of the Week, the DPMS A-15 Tactical Precision Rifle (TPR).

The World War II-era PPSh-41 was a symbol of Russian resistance to the Nazi invasion. It's an iconic firearm, well steeped in history—and also a select-fire submachine-gun capable of full-automatic fire. That makes it a Class III firearm, so examples are subject to legal restrictions on sale, ownership and transport—not to mention quite expensive.

Originally developed in close cooperation with the Israel Defense Force (IDF), the IWI TAVOR was created to excel in close-quarters engagements—and now a civilian version is available. The bullpup design moves the rifle's center of gravity closer to its handler's body, allowing for instinctive aiming and improved acquisition time to target. Better yet, its full-length barrel means no loss of down range accuracy.

The Sturmgewehr 44 was originally developed in Germany during World War II, and is well-known for being one of the first modern "assault rifles" to see major deployment. In honor of the Sturmgewehr, German Sport Guns has released the GSG Schmeisser STG-44—a replica model that's dialed back to semi-auto and chambered in .22 LR. It's being imported to the United States by ATI.

The idea of a switch-barrel rifle sounds interesting, right? It’s an intriguing thought for most riflemen and women, but typically the setback is the cost of the second barrel. Thompson/Center’s Dimension bolt-action may eliminate that issue: its list price is only $699; additional barrels are just $199.

T/C offers four caliber groups: the “A” group is .204 Ruger and .223 Rem.; “B” is .22-250 Rem., .243 Win., 7mm-08 Rem. and .308 Win.; “C” is .270 Win. and .30-06 Sprg.; “D” is 7mm Rem. Mag. and .300 Win. Mag. When demands warrants, the company envisions adding more calibers.

Famous for being the first DA/SA pistol and, of course, 007's firearm of choice (arguably more so for the latter), the Walther PPK remains one of the most famous handguns in industry history. Now the popular PPK line has expanded to include one of the most affordable calibers on the market: .22 LR.
