Fits my sa hellcat compact like a glove - SIG SAUER Romeo-Rs Compact 1x24mm Reflex Red Dot Sight

Had been looking around a lot for a compact circle red dot reflex and this is an outstanding optic from Sig. Fit my SA Hellcat perfectly - no wobble room or force to seat the base. Optics are clear, battery insertion was easy (but have to carry the T4 wrench when need to replace), all settings - Circle dot 2 and 32 MOA and Red dots are very clear and easy to change. Though motion activated on and off, have turned it off when not carrying and at minimum settings, the battery is supposed to last 20,000 hours, will see. Need to get the range and adjust the sight in. So far, outstanding product again from Sig.
