XGS320/250SCF.

The XGS320/250SCF takes the Subcompact to full-size capacity. It slides over a full-size factory SIG P320 or P250 magazine and seats it in the Subcompact. In 9mm that is 17 rounds in place of 12. For the compact magazine, use the XGS320/250SC.

On its own, the longer SIG magazine leaves a step below the frame. The XGRIP fills it, drawn to the SIG's own grip lines so it looks like part of the pistol. Its shape is based on the anthropometrics of the hand and wrist, giving the little finger a full surface to hold instead of an edge.

It is cut to seat the magazine at the right depth, and no deeper. Nothing on the pistol is drilled, cut or replaced. Made for factory SIG magazines.
