this is a 3d printed double stack version of the CP33 magazine. It requires the Spring and follower of a sig P322 25 round magazine. it needs to be printed at the finest setting possible because friction causes it to jam.
I think they will work ok once the insides are broken in, i'm getting a lot of failures to feed from friction.
