trouble extracting? Could be your chamber doesn't have enough free bore.
Took me a while to find this.

The 45 chambers can be tight and not have enough free bore. Longer cartridges extend into the rifling and prevent the pistol from going into battery or making extraction difficult. You can check your ammo by doing the "drop test". Drop a round into the barrel and see if it slips right in and seats even with the hood. There are some pictures around here somewhere. I had this problem with my CM45 so I sent my barrel out to dougGuy to get it fixed. Works fine now. Greg, gb6941, was the lead author on this topic I believe.
