Replaces the standard Sig Sauer P320 or P250 magazine floor plate with a rail adapter so you can attach the MantisX to your firearm if it does not have an existing rail, or if you want to work with holster draws. 

Please Note: This floor plate is not compatible with early grip modules of the P250 series or the X5 variant of the P320 pistol (unless using the 21 round extended magazine).

This MagRail is compatible with round and square hole baseplate pin shapes.
