I received the conversion for my G21 a few days ago and was able to get out to the range and run a variety of my handloaded ammo through it. Compared to the G30 kit that I have had for a while the 21 is more comfortable to shoot, there is much less palm slap(trying to come up with a term for it). I found that the 21 fed some semiwad-cutter loads that my 30 hiccuped with, and was flawless throughout the shooting session (after a single semi-wadcutter nosedived, third in the mag, and third round through the conversion. It ws probably caused by a little limp wristing). I'm very happy with its handling at this point, just need to get some adjustable sights, Any suggestions?
