    At a popular request -- that is to say, because a guy at a gun show asked me -- I made an adapter for 9mm SIG magazines. I based it on the old Fraurem adapter for Walther PPQ.

    It was a little bit challenging. P320 magazines are noticeably tilted, as well as fat, so the usual interference with the AR magazine latch applies.

    One thing that eludes me thus far is the bolt hold-open. I know that the factory-made adapters have that feature, but I'm not good with my hands, and I am struggling to develop a reliable design. So for now I shoot like a communist, to a click.

    P.S. The 9mm AR is very popular with ladies. It's supposed to have a greater recoil than a normal 5.56 AR, but it does not seem to, even though it's a blowback.
