With an innovative new magazine design the P365-XMACRO COMP packs a full-size 17+1 round capacity into the thin, iconic profile of the P365. The P365-XMACRO is also more shootable, with an integrated compensator that reduces muzzle flip and makes follow-up shots faster and more accurate. And with its slim, 1-inch wide design the P365-XMACRO COMP is more concealable and more comfortable to carry than any other 17-round gun on the market. The XMACRO COMP model features a slide that is milled for the ROMEOZero Elite optic with an RMS/SMS cut that can accommodate any other aftermarket optic with the same matching footprint and comes equipped with Sig Sauer's signature XRAY3 day/night sights. This model includes a pre-mounted ROMEOZero Elite red dot sight and features no manual thumb safety. Two 17-round steel magazines with high visibility followers are included along with 3 interchangeable backstrap sizes.
