*Some muzzle devices may be too long for use in the SRD or MOD-X suppressors.  You will need to reference the available information and/or contact the manufacturers of the adapter(s) and muzzle device(s) you intend to use for dimensional information to confirm that the depth of your booster housing plus the 3/4″ this adapter adds will be sufficient.

**This adapter does not make the SRD and MOD-X compatible with 3-lug mounts that utilize booster housings as spring seats.  The 3 lug mount must be self-contained, and only the Kaw Valley and SilencerCo self-contained 3 lugs are known to work.

    The fit and finish on this part is exceptional. When assembled the silencerco tri lug assembly fits perfectly with this and everything looks like it came from the factory this way. Great option for us SRD9 owners.

    I've had an SRD-9 for years wishing someone would make a tri-lug for it. After finding this I was eagerly awaiting it to come back in stock. The SOCOM black blends perfectly with the Griffin Armament tri-lug adapter. If this is in stock don't wait it's 100% worth it

    I haven’t shot this or taken it to get an alignment gauge checkup, but just looking at the lean machining and paint job I can tell they are not just turning out a cheap product. This SRD45 can is nice but I’ve always been bummed I didn’t consider there was nothing but direct thread options from Sig. This gives the can a whole new life. The Socom black is very close to the color of the Sig and SilencerCo trilug. Given it’s going to spend its time on a 9mm PCC I don’t see an issue arising, but I’m happy and ECCO has been responsive to my inquiries. Would buy from again.

    I bought the Sig SRD 9 & 45 Alpha adapter in Socom black. It arrived promptly and without any problems. It screwed in effortlessly to my suppressor and a rugged tri lug mount screwed in perfectly to the adapter. I am completely satisfied with my purchase and wouldn't hesitate to recommend Ecco machine to anyone.
