OK I have read most of the threads about FLGR both for them and against them. I have decided buy a standard GI setup to have on hand should my two piece FLGR go south on me. I just got but have not shot yet a new SA Loaded PX9109L. My question is this. Who should I buy from and EXACTLY what parts should I buy? I mean a complete list of parts you would get if you were replacing them yourself. I know I need a new plug but what else. Should I get a new spring (16lb)? Or should I keep the OEM? I went to the Wilson site but dont see any standard GI recoil parts. All they list are various two piece and one piece FLGR. Thanks for the help.
