If you’re interested in carrying a compact pistol in a caliber heavier than 9mm or .40, there are two Glock 45 ACP handguns you should consider: The G30 and the G36. Which weapon is better for your needs depends on your preferences regarding ergonomics, weight, and capacity. Both weapons are accurate, highly reliable, and suitable for self-defense.
Why 45 ACP?
Glock introduced its first .45-caliber handgun, the full-size G21, in 1990. The primary reason a gun owner selects a weapon in .45 caliber is stopping power — the ability of the bullet, when properly placed, to incapacitate an assailant.
