Sidearms & Scatterguns New glock threaded barrel in gen 2 glock 21

[Conrad101st]

So I have my trusty G21 from 1992.
Bought a new factory threaded barrel the other day.
I see that the barrel locks up nicely but I do see a very slight difference in that there is a slughtly curved up area on the bottom of the rails at the very end by the chamber verses a flat run out in the base of the chamber on the old barrel.

Can I run this new Factory glock threaded barrel in my old gen 2 G1??

Where did you get a factory threaded G21 barrel?

i have an LW that I run in my Gen2 and it works fine.

Palmetto state armory. It's m16 x 1 left handed so it matches my HK USP tactical setup.
