The Sig Sauer P320 XTEN Comp is a semi-automatic pistol chambered in 10mm Auto on a carry frame with a 3.80-inch barrel. It has an optic-ready slide, manual safety, and ships with two 10-round magazines in black finish. The carry frame size positions it as a compact option within the 10mm P320 line.

Owners who picked the 10-round P320 XTEN Comp over the 15-round variant typically did so for compliance reasons or to make the grip profile more manageable. The carry frame with the shorter grip feels balanced in hand, and most find the 10mm recoil is softened enough by the comp to stay on target through follow-up shots.

The optic-ready cut and manual safety are the same as the higher-capacity version, and opinions mirror those of the broader XTEN Comp line. Shooters comfortable with the P320 platform adapt quickly; those new to it note the manual safety requires deliberate practice to build muscle memory.

The trade-off between capacity and grip size is the defining conversation around this variant. Some owners would prefer a flush-fit 10-round magazine that trims the grip further, but the carry frame as shipped works well for concealment in most common holster rigs.
