I bought the PTR 9SDM-B about a month ago and have about 500 rounds through it and I have to say it’s absolutely amazing…..it’s a 3 stamp gun, 2 suppressors and 1 SBR.  I have tested it with 5 types of ammo from 115G to 124G and it is completely hearing safe, the only sound is the bolt slamming.  The fit and finish are top notch, and I have to say PTR customer service is absolutely top notch.  I cannot recommend it enough…..

I have one too and no complaints thus far.

Looking to put an Acro on it and put it through its paces.

Dang I am confused. How do you use 2 suppressors on one gun at the same time? Or are you just saying that you have an SBR that will fit more than one of your suppressors?

Yes sir, first suppressor is a blast chamber for the ported barrel, brings it subsonic and the second suppressor makes it quiet, like really quiet.
