Went to the range yesterday with some ammo and the 24/7 pro 45acp. I started out shooting at 25 yards at paper. I was using a pistol rest. I wanted to check the "point of aim" to see exactly what the point of impact was. I loaded a mag, settled in and shot a ten round group. I was holding the sights "dead on" and not using a 6 o'clock hold. The pistol shot pretty much on center. I loaded another mag, using the same hold, and again, shot on center. After I was satisfied how it was shooting, I switched to shooting steel off hand. I have a nice spinning target with a 6" and 8" paddles on it. After a few mags I began to miss the steel targets and the more I shot the more I missed. I began to wander what was going on. So I switched back to the rest and paper. To my amazement, the pistol was shooting about 5" low using the same "hold" that I was using to start with. By now the pistol was very dirty and very hot. And I mean real hot. By now I've shot about 150 rnds pausing only to reload magazines. Idealy the thing to do now would be to let the pistol cool down and maybe wipe out the internals some but I was just about out of ammo.
Has anyone else notice a "shift in point of impact" like this. I know that when steel gets hot it has to expand and this could in theory change how the pistol locks up and thus change the point of impact. By the way, the pistol function flawlessly.
