Time to change my recoil spring. I've lost track of what I've put through my G21 since I've had it. Somewhere over a thousand. The recoil spring assembly has been falling out when I field strip, so I thought I'd change it out to stop it from doing that too. I have a stainless rod non-captive in my G34 LWD Slide/Barrel assembly. Thinking about going to tungsten T.H.E. rod non-captive in the G21. My G21 is mainly a defensive weapon, so I'll probably stick with the 17# weight. I've started reloading for .45 (mainly for my 1911), and have been starting up some loads, I may make some light rounds and get a lighter recoil spring weight too to play. Anyone use this setup?
