    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.
