Aryeh, this is a Hybrid like the Glock G19x meaning it has a full size grip for full size capacity and a Compact Slide for a compromise between capacity and concealment (Hybrid). Cheers and stay safe!

Sig calls this an 'X Carry' which the carry line is considered compact. But its really more of a hybrid like the G19x, or the G45. It has a Full size grip and a compact length barrel/slide.

Aryeh, as for size this is considered compact. Sig has a p320 x compact Wich is slightly smaller than this the p320 x carry. I'd consider this more of a mid sized pistol because it's not quite compact but it's not quite full sized. Hope this helps.
