Not gonna happen. Sig likes proprietary systems, they make more money off them.

Fully understand the “proprietary systems” profit, but how much more profitable is the Mpx magazine over the 320 magazine. SIG also like modularity so why not make the MPX more modular by having two type of lowers. A tactical one that take 320 mags, which is also a proprietary mag and a tournament speed one. I bet the SIG marketing team could come up with a reasons why you need both. If more and more other manufacturers are coming out with a 320 magazine compatible PCC that shows there is a market. In the end every 320 compatible B&T, CMMG, aero p etc sold is less profit for SIG and is also putting another brand into a potential SIG owner hands. And while they’re at it they should add a non-reciprocating charging handle because that’s the new must have wingding.Not gonna happen. Sig likes proprietary systems, they make more money off them.
Wishful thinking. Get a B&T APC9Pro w/ 320 lower. I sure did. That and my MPX are now my favorite 9mm PCCs.Now with 30rd 320 magazine available I wonder if a MPX lower that accepts 320 magazines is far behind, makes sense for LE/Military/civilian that have m17-320s.
