P320 Lockwood Slide, 4.7” Bull Barrel

Description

Personally commissioned and designed by USPSA Grand Master Isaac Lockwood, this P320 slide is designed explicitly for Carry Optics and has the following features.

• 4.7-inch full-size slide with optimal mass balance and aggressive texture
• A custom Faxon bull barrel manufactured to Grayguns specifications and hand-fitted for the 4.7-inch slide length
• Diamond-Like Carbon (DLC) or Bead-Blasted finish

We’ve provided a fast but very soft and flat shooter by balancing this particular combination of slide and barrel mass. The red dot tracks more consistently in the window for many who have tried this combination.

Design & Functionality

“Factory barrel-fit dimensions are dictated by the possible, wide dimensional extremes between FCUs and slides. Drop-in aftermarket barrels are reverse-designed from factory dimensions as a starting point and are thus even “looser.” As a result, you see a lot of pre-lock jams, failure-to-feeds and accuracy issues from barrels that may look pretty but don’t fit or shoot worth a hoot. Few P320s deliver the accuracy of which they are capable.

I designed our barrels to eliminate gross vertical slop when out of battery for reliable feeding and function. We individually fit each of our barrels to the slide it’s serialized, for a minimum clearance working fit in all axes. They group exceptionally well. In addition, our lockup values yield a softer recoil impulse and smooth sight return, with greatly enhanced durability. Nothing else available compares.”

Lockwood P320 Slide – 4.7-inch – Additional Information

You can directly mount one of our red dot options to the slide. There is no need for an adaptor plate.

Our Grayguns Lockwood 4.7″ slides cut for the Romeo1 Pro have factory P320 XFive Legion optic cuts that will fit the newest adjustable rear sight plate, an OEM feature of the P320 XFive Legion pistol.

SIG changed the design of the sight plates when they introduced the P320 XFive Legion. Our slide cut for the Romeo1 Pro will only fit the XFive Legion adjustable rear sight base. Components can be mixed and matched, so you must check your slide and sight plate. Our Romeo1 Pro slides will fit the plate shown on the left.

The FTP Alpha 3 will not fit our slides. Although the hole pattern is the same as a Romeo3 Max, the footprint of the FTP optic is too long.
