This listing is for ONE Magazine. Smith & Wesson’s 4000 series full sized pistols had two magazine well widths, .815 inch and .818 inch. Here are quality compliant magazines for the ones with .818 inch wide wells. They will not fit the .815 width pistols. They will fit all the 4013 double stacked pistols, no problem. These are magazines to fit Beretta 96 series pistols with only an added magazine release slot for the Smith & Wesson 4000 series pistols, including models 410, 411, 4003, 4004, 4006, 4026, 4043, 4044, 4046, that have an .818 width magazine well; and any TSW variants of those pistols. Manufacturer is Mec-Gar s.p.a., of Gussago, Italy. Construction is certified heat treated carbon steel, with piano tensile wire springs, steel inner plate, and high impact polymer cartridge follower and tail piece. Finish is polished surface blued steel with full length tig welded smooth milled backs. We have added a correct width pliable rubber spacer above the floor plate. Each magazine holds 10 rounds of .40 S&W ammunition. Our local machinists have added a magazine release slot to engage Smith & Wesson magazine catches for their 4000 series pistols, but only the ones set up on right handed shooter. They will Not lock the slide open on the Smith & Wessons on the last shot, so operators will need to be able to count to Ten. These magazines will still fit all variants of the Beretta 96 pistols. They will protrude slightly from the magazine well of 4013 pistols. Magazine bodies have not been modified or altered beyond the catch slot addition. Replacement pricing for Smith & Wesson 19079 or 23934 magazines range upwards of $100 apiece. Our modified Beretta magazines, however, are less than half that price.
