Been wanting a .40 cal patriot barrel for some time and found a used one that was like 12” long and had a little pyrodex pitting in the first inch or so of the muzzle area. I wasn’t crazy about the long barrel anyway so I cut it to stock Patriot length and turned the little round section at muzzle. Also was able to get rid of the nasty hand cut dovetail for the front sight along with the bit of rust pitting. So it worked out great. That rifling says match winner to me just the way I like it. Reinstalled the breech plug with the gasoila Teflon paste.
