I've put 75 rounds through my new PT745 without a failure of any kind. I know it's not much of a break-in, but I'm hitting clay pidgeons at 10 yards with relative ease for such a small frame pistol.
I have had issues with assembly/disassembly due to the recoil springs not contracting completely. Appears that one of my springs is spreading open a little bit at the washer in the middle of the assembly. I'm going to order a new recoil spring assembly then return mine for replacement.
I'm also hoping the single stack mag gives me just a little more concealability. Personally, I'm giving up capacity in lieu of a larger projectile in the hope that my trade-off works out.
