LC9 +1 Mag Kit

thingiverse

So after designing the LC9 Follower, I decided not to shell out $40 just to have an extended mag that holds only a couple more rounds. That's highway robbery in my book. So after some failed designs and wasted plastic, I finally figured out if I design a small cut in the follower, it could clear the set screw needed to hold the +1 Baseplate securely. I wanted to make sure this design wasn't permanent. (So you can reattach the factory mag parts) I also wanted it to be easy enough that all you'd need to do is print the parts, and at most do some minor sanding and filing (of the printed parts, remember none of this is permanent) for fitment. This mag extension kit has been tested with over 500 rounds of different ammunition. I've found the mag kit doesn't really like flat-nosed and hollow-point ammo unfortunately no matter what I change. FMJ and truncated nose ammunition seems to work well though.
