Searching for "GMod PSP ISO" or "GMod PSP Download" on old forums often led to sketchy links or highly stylized concept videos. Creators would use video editing software or PSP video playback features to display actual PC GMod gameplay on a PSP screen, claiming they had found a secret, unreleased official port.

The PSP is one of the few handhelds that natively supported Lua scripting through homebrew. Since GMod addons are written in Lua, a dedicated developer could, in theory, rebuild the logic of GMod (not the graphics) on the PSP. You would have 2D sprites instead of 3D models, but the welding, constraints, and thrusters could theoretically work.
This article dives into what "GMod PSP" means, covering fan-made recreations, the use of PSP models within the PC version of Garry’s Mod, and the technical limitations of bringing Source Engine physics to 2004 handheld hardware. What is GMod PSP?

ToyBox PSP is perhaps the most notable attempt at creating a physics-based sandbox specifically for the PSP. Developed by independent homebrew creators, it allowed players to spawn primitive shapes, ragdolls, and simple objects into an open environment.
