Is that Mary I see?

The decker is a fully diy in .380acp and the 3dp90 is a a diy 5.7, so it for sure would work, the only thing in the 3dp90 that's usually not diy is the barrel, but they do include the blueprints in case you got a barrel blank and a lathe. I dunno about .45 since its such a bigger round, the bolt would have to be heavier and the upper stronger, but you can for sure do it

I also put to use the 1/2x28 inner thread with a muzzle break, for more longevity of the suppressor, this ones only gotten through about 150 rounds, its in pa6-cf

Nikolai's Machina fits it like a glove, and has a version that can be threaded into the large threads of the barrel, leaving it flushed This is my mac and cheese v2.5 with the supp for reference Also no toes for thee

No experience with .22lr cans, but for my 9mm, the quietest reading I've gotten is with the hubtn.4, he has a .22lr version, but again I have not tested it, might be worth to try it out though

My original tac9 firing pin broke on my second range session..... I bought spares from maf-arms, they were like 10 bucks, and they seem to be way better quality than the one that came with the tac upper, I bought 5 replacements and I'm still using the first one lol.

I just checked and they are out of stock, sadge, still this is the link if you wanna get notified by email: https://maf-arms.com/product/tac-chime-firing-pin-replacement/

Man almost all the tac9 stuff is out of stock

Currently my go tos are ST ppa-cf for important parts, polymaker pet-cf for nonload bearing parts(where I would traditionally use pla+ in some color, I use pet if I wanted the ash black color, or if I want it to last longer) and polymaker pps-cf for suppressors

Yeah the bipoly looks great. I'm gonna look into that version as soon as I get my parts!

I only have experience with the sl-15(hoffman) and the proof defiance, both are incredibly durable, I'm looking to make a bipoly with the a2 stock, it looks though af, so you might want to check it out aswell

I believe there was a alloy remix that was compatible, but can't recall if it was a beta or if its out
