Breaking – The P365 XL and Romeo Zero Optic

The SIG P365 was quite the gun at SHOT 2018 and since then it’s been a massive success with numerous awards and thousands adopting it as their new EDC. The P365 is a sweet gun, it’s a striker fired 9mm that holds 10 rounds in a package that is the same size as most single stack 9mms that hold 6 rounds. The P365 was alone at the top, but it’s about to get a younger, but bigger brother. Osage County Guns released the first look at both the new SIG P365 XL and the new SIG Romero Zero optic.

The information comes from an alleged spec and sale sheet, so things may change prior to the gun being released to the public. We saw little hints this was coming when the Gun Mag Warehouse published a listing for a 15 round P365 magazine. Until now that just seemed to be a SIG extended mag. The P365 XL will feature a slightly longer barrel and longer grip frame.

The P365 XL will sport a 12 round flush magazine with a 15 round extended mag. The barrel grows from 3.1 inches to 3.7 inches. What looks interesting is the fact that the frame’s dust cover looks to be the same length as the standard P365. This may be hinting towards compatibility with the 3.1-inch slide for a Glock 43X style gun.

Besides the longer barrel the gun is hosting a ton of new features. This includes a flat faced trigger, an extended beavertail, a carry magwell, and best of all an optic’s cut slide.

The slide is compatible with the Shield RMSc optics, as well as the brand-new Romeo Zero optic. The Romeo Zero optic is smaller than miniature red dot. SIG likes their cover plates to integrate a rear sight, so it’s removed when you want to mount an optic.

The Romeo Zero features an integrated rear sight, and it appears as if the gun will naturally cowitness with the P365 XL iron sights. While not confirmed I would love to see the standard P365 get an optic’s cut slide model in the near future.

Release dates point to mid to late summer, and I’ve reached out to SIG for comment, and additional details. Watch this space for updates.
