The 3.5-inch Romulus Compact is the most carry-oriented configuration in the Romulus line, and owners who choose it typically cite the compensated barrel and black DLC finish as the primary draws. The integrated compensation in a 3.5-inch package is unusual in the 1911-pattern space and attracts buyers specifically looking for that combination.

The compact frame and 20-round capacity create a tradeoff in concealability that owners acknowledge openly: the magazine length protrudes noticeably, and the grip is not particularly slim. Most buyers in this configuration report they accepted that tradeoff going in. Build quality feedback on the black DLC is consistent with the rest of the Romulus line.

The RMSc cut draws positive comments for optics compatibility, though the aftermarket for the Romulus Compact specifically is thin, and owners looking for holsters or additional support note that availability is limited compared to established compact 1911s.
