It is safe to say the round count on the FNX 45 just passed 1K. The only problems have been reloads not strong enough to cycle the heavy slide.
I fired quite a few left handed today. Supported and unsupported. Actually shot better than I expected. We did note that the M&P fired very nicely with the reloads. I was able to keep it on target even when firing it so fast it sounded like a subgun.
