Didnt want to make another thread so just editing my original one.

Anyone have a Sig Mod X 9? Impressions? blowback to the face, specifically with glocks and p320?

Original Question: I see that the Cam Lok pistons comes in Sig SRD pattern but will this also work with the Mod X 9?

This description suggests yes. I have also been told yes. I've never personally verified tho.

Yes.

All MODX SIG cans use the SRD pistons.

Can verify the SRD pistons work in my Modx 45.

There used to be a YouTube video of a guy comparing a ModX 9 and I believe an Obsidian 9, and the shooter commented on how much more blowback there was with the Obsidian. It also appeared to have less blowback from the video itself. I haven’t been able to find it again. I believe it was a gun channel out of north Georgia.

I just shot my Mod X9 for the first time yesterday. Host was an IWI Masada. I did not notice much blowback in my face. I only shot it in the full configuration on this visit. I thought the suppression was very good with 147 grain subsonic. I’ll note that the modules were very tight and I definitely needed the wrenches to separate them and I needed the wrenches to line them back up correctly. I didn’t shoot a ton, but had no issues with the spring that is not compressed at the ends and the pistol did lock back on an empty magazine. Also, I really didn’t notice the FRP that some have talked about.  Here’s a short video of part of that range trip. Hope this helps.

its got some FRP. other than that, it sounded a lot like the CGS mod 9 to me.
