P320 Modern Classic Slide, 4.7” Bull Barrel

Description

Our custom Modern Classic P320 4.7-inch slide package focuses first on the weight and balance of the slide. We’ve introduced a traditional 1911 spin with utility-driven serrations in strategic areas. Available in a Black Diamond-Like Carbon (DLC) or bead blast finish. Each custom slide features the iconic Grayguns logo.

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.”

Grayguns 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.
