A New Carry 10mm?
Earlier this year SIG Sauer followed up on its first striker-fired 10mm handgun with something a bit more compact – and I’ve have all the details and some insights after kicking one around for a couple of months.
In early 2022, SIG debuted the new caliber option for its hugely successful P320 platform of pistols: the 15+1 capacity 10mm XTen. I extensively evaluated one with box after box of punishing 10mm loads and was impressed with it, the biggest complaint being that its size limited carry options.
Well, the company has an answer to that with the new XTen Comp.
Still chambered in potent 10mm Auto and using the same 15-round flush-fit magazine as the full-sized XTen, the (gently) smaller XTen boasts a 3.8-inch bull barrel instead of the standard 5-incher as seen on its big brother. This also shortens the slide and takes some weight (a quarter pound) off the scales.

Compare in size the XTen Comp, left, with the full-sized XTen. Note they have the same height and width but a shorter frame and top half in terms of length.

Plus, it has an open-top “integrated expansion chamber” that runs past the muzzle of the 3.8-inch barrel, a design that turns it into a ported compensator that cannot come loose with firing. SIG uses this on lots of its Comp model pistols, including 9mm P320s and the P365, and the company says it drops felt recoil by as much as 20 percent.
In initial testing, I found the compensated slide on the XTen Comp to have a better recoil impulse than either the full-sized XTen or the FN 510 Tactical which I tested recently.
