No, but I shoot one on a Springfield Armory XD-M. Turns your semi automatic into a 44 mag equivalent. You need a much heavier magazine spring which makes the magazines really hard to load. Mine has a locktited compensator on it and a different recoil spring, so it’s not an easy switch back and...
I have 2 fixed sight 5.5 blued unfired old armies that I can’t get any interest in. I’ve posted them on here a couple times. Timing seems to be everything.
If you son is comfortable with the Springfield and shoots it well, consider a 460 rowland conversion. 44 mag ballistics in a semi auto. Load it with your 45 acp Dies.
I don’t like the standard grips that come on the match champion. I think they hav ugly lines, so I like the bottom pictured ones. The wood grips that come on the blued half underlug models are beautiful. They have very nice lines.
