Sig MPX or JP GMR?

Wondering if anyone is using or have used/tested the above platforms for PCC? I am currently using a CMMG Guard 9 and it has served me well, however... I am eyeing wether to purchase a SIG MPX or a JP GMR, I prefer the bolt action of the MPX my CMMG has a radial delayed blowback system which makes it extremely soft shooting. But there's hardlyt no aftermarket support for the CMMG but I love the platform. I'm leaning heavily to the Sig MPX but why does sig have to make it a propriatary mag? smh~ Anyway, anyone care to chime in? I'm sure this topic has been covered before but I'm just being anal with my future decision...

Thanks

Of the two I'd take JP all day long. Sig QC isn't what it was when they built everything in West Germany, it's downright sketchy these days.

I built mine with mostly JP internals.
