9x19mm Cobray M-11/9

DB9 BASED WITH LAST ROUND BOLT HOLD OPEN ON GLOCK MAGS AND SS COMPATABLE

This is my first 3dsquired project so there is a lot of room for improvement further testing is needed. I will be posting an updated version once it is complete that takes more common hardware the last round bolt hold open requires a reduced weight spring i will find a standard spring for my next version

upper receiver modification needed to fit the ss lever I just cut the back of mine completely out in hopes that it would be fine and it has been fine so far

HARWARE NEEDS TO BE AJUSTED TO EASIER TO FIND THINGS
originally made for micmaster-carr hardware but its just too expensive

designed for use with the aves rails upper

only takes a2 stile handgrips no back straps

I made a 3d printed knob because the one that come with mine snapped in two while shooting

printed Hoffman Tactical rounded detent

takes Hoffman Tactical ss cam

the upper model is from the dp9 release and it says it was modeled by DanishBulldog

the original model I started with was from db-firearms https://odysee.com/@db-firearms:4/DB-Alloy-Official-Release-1.0:4

I was inspired by Philz Phree Phyrearms Phoundation for how the front mounts up and how the last round bolt hold open works https://odysee.com/@philphisher:0/macaroon:3

I was inspired by 009515 for the sled idea to get the ss working

polymaker PolyLite™ PLA Pro for the lower
polymaker PolyMax™ PLA for the front and rear parts
polymaker PolyFlex™ TPU90 for the buffer (the buffer that comes with the aves kit works fine but comes apart after about 1200 rounds in my experience and conditions)

I printed with a .6mm nozzle but a .4 should work just fine
