This is the first 1911 I've owned and really like this pistol, but I do have a question on changing clips when firing. When the slide locks back after the last round of a clip and you change clips, do you hit the slide release to chamber the first round of the new clip or rack the slide back and let it chamber the round? I ask this as I've been using the slide release, but the last two times I've fired the pistol after a couple of clips it will not go to full battery. The round will only chamber about half way and requires a tap of the back of the slide to fully chamber. If I rack the slide on a new clip it will fully chamber but this method does take just a bit more time to preform. I'm using the stock clips as well as some 10rnd McCormacks with Rem 230gr JHP's. Once the first round is loaded it has never FTF in 600rnds.
