About the Gun

One of the first successful polymer framed designs, Glock handguns are common sidearms among law enforcement agencies and military organizations around the world. Although a striker-fired pistol, the Glock employs a single-action (SA) trigger, meaning that the trigger does not cock the gun, but only releases the striker when pulled. Cocking of the striker is performed by the retracting slide. Glock pistols have no manual safeties. The trigger is the only operating element. All three internal pistol safeties are deactivated when the unique single-action trigger is pulled, and automatically activated when it is released. For more information on the Glock design, please refer to the Glock pistol animation in the Basics section.

About the Cartridge

Initially made by Norma and chambered in the Bren Ten pistol in 1983 the 10 mm Auto was right off a formidable round. While the Bren Ten was not successful, the 10 mm cartridge was. In 1989 the FBI announced the 10 mm Auto as their officially favored sidearm. While the cartridge has proven itself over time, many felt that the cartridge was a little long for semi-auto pistols, making the pistol grip a little big for some comfort levels. When the shorter .40 S&W cartridge with very similar ballistics was introduced, it soon won popularity over the 10 mm round. The 10 mm Auto cartridge still has a strong following and manufacturers are still making pistols chambered for this round.

Glock is Glock, 10mm is 10mm
By DrakeCom on 17 May 2019
Like all Glocks, this model G20 takes care of business for its application. Be aware that it is full size, and is not a great candidate for concealed carry; but can be carried OWB or in a chest rig with minimal discomfort. Recoil is the factor here: target acquisition for repeat shots requires practice. It is not a pistol for those new to shooting. Best application is hunting. The 10mm is recognized in Alaska as a viable bear gun; one reason is ammo capacity, besides the power factor. And with a quality extended barrel, and proper sights, can be effective on most but largest game out to distance. Home defense is also an option. But again, repeat shots could be a problem. Additionally, there have been considerations in court proceedings as to the need for such a powerful weapon in the home. I've owned a couple of these, and now have the G20sf. I really enjoy the experience of shooting a large, powerful handgun that is a bit more comfortable all around than dealing with the 44 Magnum rev.
