Smith & Wesson 41 422 622 2206 MGSW19050 Magazine

This is a complete magazine with all parts. Magazine pin, follower and spring base are compatible with original magazines.
Unfortunately magazine body is more a concept than working part (because lips are too weak). Nevertheless magazine body fits and locks in place. Maybe you will have an idea how to finish it? Please share.
Magazine follower is modified version of Bill Hubbell's work - https://grabcad.com/library/s-w-magazine-follower-for-model-41-2206-622-1
