The launch of the P365-XMACRO redefined capability and performance in a small concealable package. With its innovative magazine design, the P365-XMACRO family of pistols packs a full-size 17+1 round capacity into the thin, iconic profile of the P365 making it more concealable and more comfortable to carry than any other 17-round gun on the market. This latest addition to the XMacro family pairs a non-ported, XSeries optic-ready slide with a 3.7-inch barrel to the innovative XMacro grip module. The slide 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. Two 17-round steel magazines with high visibility followers are included along with 3 interchangeable backstrap sizes. This model features no manual thumb safety.
