I just picked up a FNX-9 today and took it right to the range. Before shooting it I took it apart and gave it a quick wipe down and oiled the slide, the trigger parts and hammer parts. After 30 rounds I had nothing but FTE and stove pipes. It also did a lot of double feeding and not locking on the last round. I brought it home and and did a full strip and clean. It is sitting now with frog lube clp and I plan on retrying it on Tuesday. I have read letting it sit while racked open but is there any other suggestions I can try to. this is supposed to be my IDPA gun but i'm having second thoughts now.
