I have one of the early G30sf - s/n LWTxxx purchased in March 2008 right after the intro. It shoots fine however, when manually extracting rounds through the gun (full or partially filled mag), I've got to be quick and really yank back on the slide or it locks after about an inch of movement - the only way to remove the round from the chamber at that point, is to drop the mag. This is far different from my G23 - much smoother manual extraction. I know we've all talked about the G30sf mag springs, how they are stiffer than hell but do loosen up a bit in time and am wondering if its the mag spring that's causing this (I ordered the newer G30 mag springs but have not received), I also noticed that my G30 mag followers are getting more chewed up compared to my G23 followers. I just ordered the new 4256-1- trigger bar from Glockparts to see if it will make any difference. I have already tried various recoil spring assemblies - stock and Wolff, no difference there. Thanks. Any insight would be appreciated.
