Alittle confused as to what is factory standard load and factory hot load. I've looked up Hornady, Federal and Silver Bear and they are 1000fps in 95gr.is the lowest and Buffalo Bore +P 115gr. at 1000fps. and Fiocchi 100gr. is 1065fps. Looking at other sites about the Mak it's said not to shoot hot loads alot like Hornady XTP. But their load is 95gr. at 1000fps. These sites also say if you do shoot hot loads put a Wolf 19# recoil spring in gun, vs. the factory 17# spring. When my pistol comes in from J&G sales I'd like to know what I'm doing here before I shoot it for the first time. Would a 19# spring be good to put in anyways cause this pistol will be used for CCW and I was going to use a mixture of Federal 95gr. FMJ at 1000fps and the Hornady XTP in the mag. for carry. Is my OCD working overtime again or is this not worrying about? Any info is always appreciated. Thanks guys.
