Thanks for the tip. I will check the serial numbers close and do a good visual inspection.
Won't be counting on it for CCW until I put about 1000 rounds through it.
That should shake out any problems.
After reading the rest of the posts I don't think I'm going to buy the PT145. It seems like the problem is a design flaw and will keep happening until they make a design change.
Might get a 1911 instead or glock.
