M11A1 MAC-11 Modification To Accept Glock Magazines

And converted from .380 to 9mm:

Was constructed from a .380 small MAC and a CCF Raceframe aftermarket stainless steel glock frame ($320).

The modification definitely improved ergonomics.  The rate of fire (ROF) is apparently comparable to a Glock18.

Another clear advantage of this conversion is that the 33 round 9mm Glock magazines (~$30) are less than 1/2 the price of the OEM 32 round zytel (plastic) Cobray magazines.  This is going by the $75 price on Cobray’s website , although the magazines do appear to be available for cheaper on online auction sites such as gunbroker.

One thing you’re giving up by doing the conversion is the ability to use these awesome aftermarket 58 round magazines available for 9mm regular MAC-11 conversions :P

  1. Wow, those 58 rounders are epic. That would be pretty heavy fully loaded though.

    1. On the other hand……in a pinch it would make a great putter.

        LOL definitely!

      2. So with its open bolt design, would that be considered an AD or a ND when a putt inevitably sends a burst of 9mm down range?

      3. Do you ship.just need a steel m11a1 frame.internals not needed but will buy of needed to

        1. Is this frame metal or polymer?

      Yea with the high ROF of that gun you’d probably have to compensate for some pretty extreme muzzle rise when doing a 58 round mag dump :P

  2. Finally I can get the comfort of a glock, without having to worry about KABOOMs! Whoever made that should go into production full speed.

      Yea I think it would probably be pretty popular, although there would be a pretty small market.

  3. I’m gonna wait for the 50 BMG conversion…..
