I picked up a LEO surplus G17 - I field stripped it and gave it a good cleaning - my first time at the range with it yesterday, I experienced a few jams - FTE, I think it's called. I was thinking that, being it's a used gun, I just needed to replace one or more of the ejector components, but now I'm wondering if it's related to the Berdan primers?? The ammo is military surplus - "Caliber 9mm Ball (9x19) MK 2Z, SMC, FMJ ammunition. Mfg. P.O.F. in 80's. Brass cases, Non-Corrosive, Berdan. 124 grs." - I had issues with some 7.62x39 mil surp ammo that had Berdan primers in my AR-15, and I had to mod the firing pin and get a heaver hammer spring so the rounds would get harder strikes - the AR runs fine now. I bought the ammo for a FA gun I have - I'm having some magazine problems with it - now I'm wondering if the ammo is suspect? Any suggestions?
