FACTR™ SIG® Magwell for P320 XSeries

In the search for an effective magwell to run on our guns without drastically increasing the profile and size of the bottom of the grip, we kept coming up short. Too wide. Too tall. Funnel too small. Not enough funnel angle at all. Poor grip enhancement. Ugly as sin. That's when we decided that FACTR needed a magwell of its magwell to rule them all...just kidding. However, we believe the FACTR Magwell checks all of the boxes in the search for an effective and concealable CCW magwell. It adds significant reloading functionality with a minimal EDC footprint. It also provides grip enhancement by giving the user a comfortable index ledge for the hanging pinky...more of that digital comfort you've come to expect from us.
