The AXG frame in stainless steel with nitron finish. I would also be happy with all stainless P220/P226, no rail or tail.

P226 SAO in 357 sig, Legion or regular ... rail or no rail.

A 226 stainless that looks similar to the X5.
Make 3/4 versions of the grip modules for the P320.

Stop all assembly lines for all other pistols and convert them to P320 parts and quadruple the production hheeee! LOL
