Glock 26 with a P80 slide added. Has a cut out for a red dot and comes with a 10-round magazine. Has seen very, very few rounds. Barrel is NOT threaded. **** I am an FFL based in Belton. You'll need to come to me, fill out paperwork, and pass a background check. **** I have posted this before, but ran into a family emergency. I apologize if I didn't get back to you - please reach out again if you're interested.
