Having some limited experience with 1911s, I was very excited to get an
FNX-45. I can carry one in the pipe uncocked. I've got DA on the first shot. I've got a decocking lever. It holds 15 plus that safer friend in the chamber. It is also a dream to break down, clean, lube, and reassemble compared to 1911s. There is one catch though.
After firing 75 rounds through it, my thumb was killing me the next day. In fact, it is still sore almost a week later. I never had that problem with other similar calibers so I can only chalk it up to loading the magazine. The first 8-10 go in easily. After that, it gets increasingly difficult. The 15th is downright ridiculous.
I just wondered if anyone else had this problem and how they deal with it.
