You may know this already but the 1911 needs plenty of lube in the right places. As far as malfunctions, if you can describe what type of malfunction we can help you diagnose it. It could be alot of things, lube, magazines, extractor tension, chamber depth or limp wristing among other things.
First off, I can tell you that I have a very manly wrist.
Secondly, The scratches must be normal then because they look very machined and wore in but they worried me because in my line of work I am used to using just a 9mm Beretta (Which I hate) so I wasn't sure if they were supposed to be there or not. The round simply doesn't seat. Thats what happens when it jams, it will happen randomly after extraction and before the next round is seated. Before the round is seated it just simply stops, this also happens occasionally when I am first chambering a round, and I'm honestly not really gentle with it. The sound of a weapon charging and hearing a round seat is probably one of my favorite sounds, so I like it loud. Its always the same issue, its completely random and I thought it may have been an issue with a medium-priced round I was buying so I picked up a couple boxes of more expensive rounds and it didnt stop the issue. To correct it, I need to pull back on the slide enough where it pulls the round off of the part of the chamber by the ejection port and release the slide the completely seat the round. Maybe if I caught it I could get a picture of it but for now I guess I will wait to see what other offers roll in. I cant just send in my current barrel to KKM, Can I? I was under the impression that I need an extended barrel so that the suppressor does not interrupt the cycle of functions....
Thanks for the input.
