Frequently Asked Questions

What are the key considerations for reliability when shooting hot 10mm loads in a Glock 20?

For hot 10mm loads in a Glock 20, reliability is enhanced by using a heavier recoil spring, such as a 20lb or 22lb Wolff spring, and ensuring adequate chamber support, potentially through an aftermarket barrel from Lone Wolf or Storm Lake.

How does the Glock 20 SF compare ergonomically to other Glock 20 models?

The Glock 20 SF (Short Frame) and Gen 4 models are often preferred for their improved ergonomics and control compared to standard frames. This enhanced grip can significantly aid in managing the substantial recoil generated by potent 10mm Auto ammunition.

What ammunition velocity was achieved during the Glock 20 10mm test?

During the test, the Buffalo Bore Heavy 10mm 200-grain FMJ-FN load achieved an average velocity between 1150 and 1190 feet per second (fps) from the Glock 20's standard barrel, slightly under the manufacturer's claim of 1200 fps.

What is a recommended strategy for bear defense ammunition with a 10mm pistol?

For bear defense using a 10mm pistol, a balanced strategy involves carrying a mixed magazine. This typically includes 200-grain Full Metal Jacket (FMJ) rounds for deep penetration through bone, alternated with 180-grain hollow-point rounds for effective tissue damage and expansion.
