Owners of the Cimarron Frontier in .44-40 tend to be period-correct enthusiasts or cowboy action competitors who want the authentic cartridge to match the platform. The 7.5-inch barrel gives it a distinctive long-gun feel in hand, which most owners find appealing for the style but note is less practical for everyday carry use cases.

The case-hardened and blued finish draws consistent praise. Most owners say the color case hardening on their examples shows good pattern variation, and the blued cylinder and barrel complement it well. Walnut grip fit is rated as good, though a small number report minor fit issues at the grip frame junction.

On the action, the Old Model configuration requires deliberate half-cock loading technique, which experienced single-action shooters accept readily. First-time owners sometimes find the action stiffer than expected out of the box, with most reporting a noticeable improvement after a break-in period.
