The RM1C has a following among buyers who want an optics-ready 9mm with a two-tone FDE and black look. The Tenifer finish on the slide gets consistent praise for durability. The RGT grip texture divides opinions, with most finding it adequate for control while some prefer more aggressive texturing.

At 4 inches, the RM1C sits in a practical middle ground that most owners find workable for both carry and range sessions. The Picatinny rail adds light and laser compatibility, which is well-received. California-compliant 10-round versions occasionally draw criticism from buyers who would prefer standard capacity configurations.

Build quality for a newer manufacturer like Rost Martin draws cautious approval from most owners. The common concern is long-term parts availability and support. The FDE frame with black slide combination is one of the most noted aesthetic positives for the RM1C among buyers.
