I was wondering if anyone has noticed if there is a quality difference between the older ones and the newer ones. The reason I ask is because I picked up an older pt 138 for 125.00. The gun was in great shape and hardly looked like it had been shot. I got it home and one of the magazines would not stay in the gun. I sent it back to Taurus to get fixed and I got it back but it wasn't fixed. To make a long story short I just sent it off again for the third time to get fixed. I am thinking about getting one of the 45colt/410 but I am a bit worried because of all the problems I am having now.
