Owners of the Cimarron Thunderer in .44-40 generally appreciate the birdhead grip profile, which makes the short-barreled revolver easy to carry and quick to draw. The blued and case-colored finish gets positive remarks for its classic appearance, though some note that the case coloring depth varies unit to unit.

The .44-40 chambering connects the Thunderer to historical single action tradition, and owners who handload particularly like the cartridge. A common observation is that the 3.5-inch barrel makes for a handy but loud revolver, with felt recoil that some find sharper than expected compared to a full-length-barreled single action.

Build quality impressions are generally solid for the price point, with the walnut grips drawing consistent praise for fit. The trigger pull splits opinions: some find it crisp and appropriate for a single action, while others feel it could benefit from a competent gunsmith's attention out of the box.
