The Zaffiri Precision ZPS.3 slide for Glock 43 with RMSc cut is a precision-machined aftermarket slide built for shooters who want to upgrade their carry or range gun with a red dot optic. Machined from billet 17-4 stainless steel and finished in Armor Black Cerakote, this slide is engineered with the tight tolerances Zaffiri is known for—the kind of build quality that translates directly to improved accuracy and reliability when you need it. It's 100% manufactured in the USA at Zaffiri's facility in Largo, Florida, and comes pre-cut and pre-coated, so you get a refined, finished piece ready to drop onto your G43 frame.
The RMSc cut on this slide accepts Shield RMSc, Holosun 407K/507K, and Sig RomeoZero optics without modification. Zaffiri engineered the footprint with no rear lugs and slightly lowered front lugs, making it compatible across all three major optic platforms on a single cut. You'll get the optics cover plate and screws in the box—critical details that let you protect your optic when it's not mounted and secure it properly once it is. The slide uses 6-32 thread screws; blue Loctite is recommended for retention, and you should respect the optic manufacturer's torque spec to avoid damage.
One important note: this slide is not compatible with Zaffiri Ported barrels. If you're running a ZP Ported barrel, you'll need the ZPS.P or ZPS.4 models instead. The G43 and 43X frames don't require a channel liner, so you're good there. The slide ships unassembled—no internals included—so you'll be installing it on your existing Glock frame.
