I took my springfield 1911 custom shooting today. With the slide locked back I insert the clip, hit the slip lock and when the slide slides forward the ammo jams. Some times I can push the slide forward and it loads all the way other times i have to pull the slide and load another. It did this a few times. It also some times would jam while firing. I could push on the slide and it would fully load. I was using blazer brass ammo and a brand new looking wilson clip. And on some of the jams there was a dimple left on the bullut.from it jaming at the barrel. I'm going to give it a good cleaning tomorrow and going over what else should i check.
