USA – -(Ammoland.com)- At SHOT Show 2015, Glock unveiled a new pistol that flew a bit under the radar as people were clamoring for a Glock Carbine or a single stack 9mm.
That pistol was the Glock G40 Gen4 in 10mm with a 6″ bbl and 9″ slide with the company’s new MOS option (modular optic system).
We might still be waiting on the carbine and the single stack came out just prior to the NRA show earlier this year in the form of the Glock G43 Handgun, so we decided to try out the G40.
This model is the most powerful Glock pistol in existence and the biggest one the author has handled (the G41 in 45 ACP is the same size); so much so that we started calling it GLOCKZILLA at the beginning of the test period.
About the 10mm Round
For those who are unfamiliar with the 10mm round, here is a short history.
Dissatisfied with the performance of the 9mm cartridge in the 1970s and 1980s, a round was sought that would replicate the ballistics of the 357 Magnum round in a semi auto pistol. The result was the 10mm, but due to the pressure of the round, most existing platforms could not be used.
A larger framed pistol based on the CZ75 was the first candidate (known as the Bren Ten) and the 1911 frame was adopted in the form of the Colt Delta Elite in 1987.
When the FBI decided to adopt the round, Smith & Wesson adopted their double action 45 pistols to chamber the round in 1989, Glock followed two years later with their G20 Pistol.
Alas, the agents of the FBI found the recoil too harsh and a new round was created (40 S&W) with a reduced load and a shorter case that allowed the round to be chambered in 9mm sized pistols.
The 10mm cartridge would have perished, had it not been for a large fan base that cherished the qualities of the round for hunting and the sheer power factor of near Magnum handgun performance in a semiautomatic pistol.
