    I have been told by Kebco that the LPA rear sights are all the same. The historic difference between the rear sight profile on Sport and Gendarmerie models no longer exists.

    On the M&P 340 (scandium J frame) I recently went through, I noticed that the recoil shield ramp was getting pretty heavily marred just from all the opening and closing of the cylinder I was doing going through the gun. Looking at it under 10x magnification, it was clear that the tip of the center pin had tool marks on it, essentially concentric grooves making it act as a circular file on the frame of the gun when opening and closing. Gave it the old 320/400/600/worn-out-600 treatment, and it is as smooth as I could want under magnification. Will make checking and addressing that the first step with any future S&Ws.

    Haven't had a chance to check out the axe du barillet on a Manurhin yet, but the gun in the picture certainly suggests tool marks could be present anywhere.

    That's not a reflection of pounding from recoil or rough machining.

    Look at the cylinder. One tine of the extractor star isn't sitting flush with the cylinder face. The pattern on the breech face is consistent with getting gouged by the extractor star. I can't say if it wasn't fit right or if it was disassembled and not reassembled correctly.

    A hardened sharpened edge will dig in against a hardened flat surface. Has nothing to do with the metallurgy of the parts in question. Has to do with the fitment of them.

    If the extractor star had been correct/corrected or is corrected that issue will stop.

    Since this is a pre-Chapius gun, the fitment of it cannot be used as evidence that the current guns built by an entirely different company, would have the same issue.

    Careful inspection of any gun before taking possession of it should be the norm.

    As it is, someone forked over the cash for that gun, because of when it was made and lack of import marks, not to shoot it heavily.
