I picked one up last year. I have a 9mm and love just shooting it, but I prefer the .45 for defense use. I have only shot it about 100 rounds. Not enough to break in the tube but at ranges to 50 yards the shots go right where I point. I would like to do some work on the trigger, but will have to wait till after some other projects.
I like shooting the carbines very much and have the .45 loaded and ready for home use.
