Chiappa M1-22 Magazine

Aftermarket magazine for the Chiappa M1-22 rifle.

I printed this mag upright @ .100 micron layer height with supports (supports only needed for the retaining plate slot). I tried printing one at a .200 micron layer height and it does seem to work but sounds more like a washboard when the follower moves up and down. (.100 microns is much smoother) The rear locking lugs do not need supports. Instead, I added a 40 degree climb working up to them to save material and negate any need for supports. After the print is done, you'll need to cut the angle off with a razor blade, to make the bottoms of the lugs square for proper fitment into the mag catch. Everything is printable except for the spring, you may be able to find a suitable replacement at your local hardware store. I left out the viewing window on the side of the mag. Frankly, I never used it any way, and it's just another way for contaminates to get into the mag.

Removal of the supports can be a bit tricky, but not impossible. I used a dental pick with great success. Also a few spots may need to be trimmed up a bit with the razor blade just to help smooth up the followers flow.

I used Proto Pasta Carbon Fiber PLA for the print and its seems to be working great, Everything fit together very well with very little prep work. Also as a side note... The M1-22's have a set screw for adjusting the amount of play the magazine has while in the mag bay. This set screw may need to be adjusted for more reliable feeding.
