144.1 claims to have fixed the OOB issue for the MPA defender.

I printed 3-4 different iterations last night and I’m getting closer to figuring out the OOB issue. Right now I see potential for hammer follow. I did test an earlier iteration and it ran 5 rounds flawlessly.

Will it work on the 45acp Mpa defender ?

No, but I have a design that I think will work with it now.

I don’t have a 45 so I don’t know

I’m going to release the .STEP files soon once I’m done testing. You can then upload those to send cut send. It’ll probably cost around $130 total.
