I have a new KKM 10mm conversion barrel that fits in a G41 or G21. It has been installed and never shot. The reason for selling is because I ended up buying a custom slide, internals and different KKM barrel that is compensated. It will also come with the required 22# spring and rod that is required for 220gr loads, it is due to arrive tomorrow (08SEP26). As you can see int he pictures, it is as new. No wait time like I had to for several weeks. Just buy and drop in and go!

This is the exact one from their site
KKM 41-10MM

PP F&F or Venmo accepted. Will ship out next business day and send tracking. Thanks.
