I have a 10 year old PF-9 that never had a FTF or FTE. I used what I think is basically an excellent upgrade kit from M-Carbo. Went to the range and fired S&B, Winchester and Magtech 115 gr FMJ. Each brand had occasional light primer strikes and FTEs. If you did the full upgrade did you have similar issues? How did you solve them? Did you find ammo that was 100% reliable and if so what brands and type? Should I switch to +Ps? Will the Keltec withstand +Ps?
If the only answer would be to remove the aftermarket springs in what order should I go about it, e.g. hammer or firing pin or trigger first, then which?
Thanks for your input.
