Lantac Razorback Slide For G19 Gen 4
Lantac Razorback Stripped Slide, Glock 19 Gen 4
So you want a slide that looks as serious as it functions, not a factory clone. This slide delivers that. The Lantac Razorback, stripped configuration, built for the Glock 19 Gen 4. Machined from 17-4PH stainless steel. Aggressive styling, RMR cut standard.
This is genuine Lantac Razorback Slide For G19 Gen 4engineering, made in the USA. First, the slide is machined from pre-hardened 17-4PH stainless steel, bead blasted to a satin finish. Next, it’s coated with a DLC finish using the PVD process, built to outlast a standard factory finish. Finally, window cuts reduce weight without sacrificing the slide’s structural strength.
Will this Lantac Razorback Slide For G19 Gen 4 fit my Glock 19?
Yes, if you run a Gen 4 G19. So this stripped slide is specifically machined for Gen 4 dimensions. However, Lantac Razorback Slide For G19 Gen 4 also sells separate Razorback versions for Gen 1-3 and other generations, which are not interchangeable with this Gen 4 slide. Therefore, confirm your exact frame generation before ordering.
What does “stripped” mean for this slide?
No internals included, just the machined slide body. So this version ships without sights, firing pin, extractor, or other small parts. Therefore, you’ll need to source those components separately, either from your factory take-off parts or new aftermarket pieces, to complete a functional slide assembly.
Does this slide come with an RMR cut?
Lantac Razorback Slide For G19 Gen 4 Yes, standard on this slide. So the Razorback includes an RMR optic cut as a built-in feature, not an upgrade option. Also, a blanking plate ships with the slide, secured by Torx head screws, for situations where you’re not running an optic. Therefore, the slide carries continuous, matching grip texture across both the slide body and the cover plate.
What makes the DLC coating different from a standard finish?
Real wear and corrosion resistance, not just looks. So the Me-DLC coating used on this slide has an extremely low surface friction coefficient, along with high micro-hardness in the 1000 to 2000 HV range. Also, this coating is chemically inert. Therefore, Lantac states this finish can extend part lifespan well beyond a standard factory coating under normal service use.
Who is this slide best for?
This Lantac Razorback Slide For G19 Gen 4 fits Glock 19 Gen 4 owners building a custom pistol, including Polymer80 builds or factory frame upgrades. So if you want a distinctive look paired with real engineering behind the coating and cuts, this slide delivers that. Also good for builders who plan to install their own internals and want full control over which small parts go into the final build.
