Moving the Holosun 509T between pistols
Page last updated . Data compiled September 2026 by the site administrator.
You already own it. Here is what changes from one slide to the next: the plate, the screw thread at each joint, the torque, the tools and any thread trap. 8 kinds of slide, covering 48 pistols, grouped by how the optic mounts and then alphabetically. Nothing is ranked. The Holosun 509T page has its specs and the per-pair answers.
8 of the 8 blocks have a figure marked not on file: no maker publishes it where this site could find it, so the plate maker or a gunsmith is the source. How the data is checked.

Steps and safety: installing a red dot, from the makers' manuals. Mounting an optic is gunsmithing; confirm the pistol is unloaded first. Screw length is never listed here because it depends on the whole stack: each pair's build sheet has a calculator that works from your own caliper readings.
