Owners of the SIG SAUER M17 in black finish often favor it over the coyote variant for its lower-profile appearance. The 21+1 capacity is a notable attraction for those who want high-capacity without a magazine extension, and it comes up frequently as a primary reason for the purchase.

The manual safety divides opinion among semi-auto pistol buyers. Owners coming from Glock or Smith platforms sometimes find the extra step unnecessary; those who trained on traditional double-action or 1911 platforms appreciate it. In either case, most report that engagement and disengagement become natural after a modest break-in period.

The M17 in this configuration competes directly with other full-size polymer-frame 9mm pistols at the premium tier. Most owners consider the optic-ready cut and manual safety combination worth the price difference over budget alternatives, though a few note that the base price does not include an optic and the additional cost can push the total outlay higher than expected.
