Please specify if you are a certified Glock armorer.
My question is fairly simple. I've read countless threads about down-converting (large caliber down to 9mm). Most of what I've read would lead me to believe I can't up-convert my 9mm to a larger caliber.
However, I bumped into a guy at the range a while back who claimed he was a certified GA. He told me it was possible as the frames on the G26 and G27 were the same. (and the .357 sig i think, can't remember the model #)
He told me you'd have to change the barrel, slide and recoil spring.
Part of my reason for asking is ammo availability. I'd prefer not to shell out another $500+ on a new gun just to ensure I can find ammo to feed the little beast.
I know, I know. "why didn't you just buy the .357 sig in the first place, dummy! Then you could drop a 9mm barrel in and go"
Hindsight, lessons learned, etc.
I specified CGA's because they know Glock's the best, and I'm more inclined to believe them if they tell me the guy at the range was a wack-job.
