Originally manufactured in 380 ACP (aka 9mm Kurz) configuration, this example has been altered to chamber 9mm Parabellum, with the magazine well extended to accept a modified High Power magazine, chamber altered, bolt shortened, heavier buffer installed and the original "9mm K" caliber stamp on the receiver altered to read "9mm P". While no documents were supplied with the lot to say who did the work, an included copy of the August 1982 issue of "Eagle" magazine has an article featuring the "Maxi Mac" M11 conversion executed by Tim J. Kader (dba TJK of Elyria, Ohio), with the included pictures closely matching the alterations on this SMG. Blade front and peep rear sights, with a threaded muzzle, swiveling base for a front web grip (not included), "S.O.F." on the front of the upper receiver, selector switch on the right, safety on the left, and a two-position telescoping buttstock. Three magazines (aftermarket High Power mags professionally altered for compatibility with the M11 mag catch) are included, as is a styrofoam carton and the aforementioned publication.

Very fine, with 90% of the original matte phosphate finish, showing areas of brown patina, bright edge wear and mild handling marks. The grip is damaged, with pieces absent, currently secured with tape. Action is stiff, but in fine order. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.

Designed to use a combination of ported expansion chambers and wipes for sound moderation, with an overall length of 11 1/2 inches and insulating foam cover over the tube sections. A short thread adapter (male side compatible with the silencer, female side compatible with gun A's muzzle) is included.

Fine overall. A few spots of rust and some mild handling marks are present on the tube sections, and the covers show scuffing and tears. Some oxidization/residue is present on the wipes, which appear little fired.
