I was trying to find out if the Gen 4 G21 glocks with the new recoil spring assembly can be converted. However RYG has a conversion kit and a 24 pound spring!
Yes you can, I called my Bud today and ask specifically, he has gen 3 and gen 4 21's in 45 Super, he said something again about a bushing for the gen 4's stainless steel guide rod.
