I found also that .357 and .358 bullets tend to shoot more accurate in most 9mm's, if they will chamber. Most 9mm's will accept .358 bullets.

The chamber support in gen 3 Glocks on up, are better supported underneath, giving a better safety factor. When a Glock KB's, it's usually the unsupported bottom of the case that ruptures, allowing hi pressure gasses to blow out the magazine, and grip. 40's are most susceptible to this, due to the dynamics of this cartridge. I have gen 2's and gen 3's, so I am keenly aware of this.
