    Just below the panhandle of Texas
    The slide on my Coonan Model B .357 semi-auto was replaced in the mid '90s due to a crack at the front sight set-screw. What I didn't notice was a machining error in the new slide just below the firing pin hole. Over time, the defect was aggravated as the rim of the cartridge slid over it when stripped from the magazine upon firing.
    This created just enough drag to prevent the slide from going into battery starting in 2014. A light polishing would alleviate the problem for a bit, but the malfunction would return after about a hundred or so rounds. You can see the defect as a horizontal line just below the firing pin hole
    Thanks to an article in American Handgunner, I contacted Don at Pullman Arms. I explained the problem and sent him the slide. Two weeks later I received the slide back. He had welded the defect and smoothed it out. A quick trip to the back yard and eight rounds fired without a hitch. I'm looking forward to shooting it a lot more to see how the fix holds up, but I'm highly optimistic.
    It felt good to feel that nice recoil again.
