5906 Mag blocker

thingiverse

Magazine blocker to block Smith & Wesson 5906 factory 15-round magazines to accept only 10 rounds and comply with laws. This should work on all Gen 3 magazines, but testing is necessary. Printed in PLA with a perimeter and one shell, about 20% infill for plenty of strength. Print one and if it doesn't fit inside the spring easily, scale it down by a percent or two. Mickey mouse ears help hold it down during printing; remove them with an exacto knife when done. This installs inside the magazine's spring. Disassemble the magazine to put this blocker in place. The sloped top is actually the bottom; line it up with the angled base plate. Epoxy the hole in the base to make a "permanently" blocked magazine, allowing you to sell 15-round magazines in certain states.
