Hello GT, I have recently purchased a Glock 39 and I am wondering what is the best defensive loading I can use in the G39 (remember its a a sub-compact so it has a short barrel). I have heard that bullet expansion can be hindered due to such a big round coming out of such a short barrel so I might want to get a lower weight grain round (ie. the 185gr. or 200gr.) so that bullet expansion can be better because they have higher FPS. Here are my options: .45 GAP 230gr/850 fps .45 GAP 200gr/970 fps .45 GAP Reduced Recoil 185gr/1090 fps (Why do they call this reduced recoil?) Which would be the best and why as far as personal protection and stopping power? Thanks Wanna kill these ads? We can help!
