Stumbled on this at random over at AIM surplus.
There are several magwells for the P320 X series grips but none that I’m aware of work with the 10/17 round P320 mags with the standard base plate. All require either the extended 21 round mags or the legion magazine baseplate.
The Align Ractical apparently works with the standard mags and claims to have an integral over insertion stop.
This is interesting since as discussed elsewhere my agency has experienced some over insertion issues with the factory magwell and factory 21 round mags.
