Hi guys. looking for a little help here. I have a 7tcu that is used but new to me. having alot of problems getting the cases in and out of the weapon.they are hanging up on the extractor. I have full length sized and trimmed to length, and scrubbed the chamber. is the extractor easy to remove/replace? any ideas or suggestions??? love the pistol, very accurate but it's a pain to load/unload. help! dcl
