What pistols fit the Viridian RFX45?

Page last updated . Data compiled September 2026 by Andrew Terrebonne.

It uses the Aimpoint ACRO footprint and mounts to 68 of the 178 slides tracked here, 1 of them with no adapter plate. An enclosed-emitter optic, with a 3 MOA reticle.

Same slides, different optics

5 other optics on the Aimpoint ACRO footprint go on the same slides as the Viridian RFX45, so the table below answers for them too. What tells them apart:

Sight co-witnessDepends on your front sight height, which can vary by SKU and production run within one model. Standard-height irons: no co-witness. Suppressor-height irons: low in the window at best, since enclosed emitters sit tall. Mounted directly, the optic sits as low as the cut allows, but an enclosed housing gives most of that height back. That's the typical case for this kind of optic, not a guarantee: pistols don't standardize sight and optic heights the way rifles do.
Aimpoint ACRO footprintThe enclosed-emitter standard. It clamps to a rail instead of bolting through: on a plate the plate carries the rail, and on a slide cut for it directly the cut can take over the rear sight dovetail. It sits tall either way.

Cost to mount is the optic plus the cheapest plate that fits, in approximate street-price bands from September 2026, for comparing routes. Pistols aren't priced, so when slides tie, the card names the most popular one.
