I'm waiting to receive my CGS Mod9 which comes with a standard 1/2x28 piston, and I'm trying to figure out what parts I need to order to run it on a Sig P320 and Sig MPX. I've ordered a threaded barrel for the P320, so both firearms will have 13.5x1LH threads.
For the P320, I think I just need to order a 13.5x1LH piston from CGS. What do I need for the MPX? I see they have a spacer; do I use that with the piston (in place of the spring)? I also see a three lug option, but no direct-thread / fixed mount option.
What would you recommend in this situation?
