I have an early 5 digit serial contender that came with a 44 magnum hotshot barrel. The hotshot octagon barrel works fine, opening and closing easily.
I just picked up a super 14 in 7tcu that will not open on the frame without removing the hinge pinand coercing with much frustration and cussing.
The 44 mag barrel has a one piece bolt and the 7tcu has a 2 piece locking bolt/lug. I've been looking all over and can't seem to find a solution.
Multiple sites say to "stone" the locking bolts/ lugs, however the older posts no longer have working pictures. It also appears like there are no longer any one piece locking bolts/lugs to be bought to switch out with the two piece that isn't working on this frame.
Any help is greatly appreciated. Also not sure what "stone" to use or where to apply?
