Same Sig Sauer Romeo-RS enclosed-emitter pistol red dot as the 3 MOA version, but with a larger 6 MOA dot for faster close-range acquisition. Compact footprint for slim subcompacts.
Specs:
6 vs 3 MOA on a subcompact carry pistol: 6 MOA is generally the better choice for self-defense use — slim subcompacts are short-range tools, and the bigger dot is faster to find. Choose 3 MOA only if you regularly shoot precision drills at distance.
