Frequently asked

What pistols fit the Vortex Viper?

55 additional pistols support it via an adapter plate, such as the Beretta 80X Cheetah and Beretta 92GTS.

What footprint does the Viper use?

The Viper uses the Docter footprint. This is a recognized cut that many pistol manufacturers mill directly into their slides or support via optic plate kits.

Can I mount the Viper without an adapter?

55 pistols need a slide plate: the SIG P320 X-series, Beretta APX A1, Walther PDP 2.0, Canik METE and 6 more plate systems carry a plate that presents the Docter footprint.

How do we verify which pistols this optic fits?

Each pistol fit is derived from verified footprint specifications and, where applicable, confirmed adapter-plate data. Every claim is backed by 1 source URL, and we cross-reference manufacturer slide specs and optic dimensions to ensure accuracy.
