So I've been using this gun for awhile and I've put about 400 rounds through it and another 100 Critical Duty and I've decided to start carrying it. I just wanted to ask a few question at which point should the recoil spring be replaced (approx round count to maintain reliability) and other parts to replace. Also where I can I send it in to get night sights installed I understand armscor has a "novak style almost" but I am no gunsmith whatsoever so I could use some info.
