Is the SIG Romeo-X any good?

The Romeo-X is a strong, modern entry. It comes in open (Compact) and fully enclosed (Pro) versions, so you can match it to a range gun or a hard-use carry pistol. You get a wide window, a no-zero-loss top-loading battery, motion activation, and a circle-dot reticle option — feature-for-feature competitive with Holosun and Trijicon. For a serious carry gun, get the enclosed Pro; for range use, the open Compact is fine. Just confirm the footprint matches your slide.
