Greetings all, After years of wanting, I recently became owner of a new Kahr/A-O TM1. This past weekend was our first outing at the range. I put 150 rounds through with almost no problem, a great way to start. My question is this. I have the new Kahr 30 round mag and a Kahr 20 round mag. I believe both to be new production as the mag catch holes are round. Both lock into the gun securely. Feeding was reliable except every now and then from the 30, and every time from the 20, the bolt would lock back with one final round remaining in the magazine. Would it be correct that the most likely culprit is the bolt catch tab on the mag follower and the solution that said tab just needs to be taken down ever so much? Thank you in advance for you courtesies with this! Happy new owner, John
