Gentlemen, I am looking for personal experience feedback if possible. I have sorted through all of the posts I can find, been researching online, and the best I can come up with is KKM and Lone Wolf barrels. I am leaning towards KKM because I have heard that LW sometimes make their chambers too tight and this can lead to malfunctions. Since the 10mm I will be testing and carrying (Buffalo Bore 220 grain Hard Cast) is almost a buck a trigger pull and I am not that gunsmithey enough to identify minor indicators of a mismatched barrel, I'd like to have something that works well right out of the box. If any of you can chime in with specific examples, and I'm going to get picky here: shooting 10mm Buffalo Bore Hard Cast from a KKM or Lone Wolf, I'd appreciate it. Thank you very much my friends!
