I recently (finally!) received my SRO 5MOA, got it mounted and zero'd on my Shadow 2 OR. Lots of fun running basic skill drills with target focus - by the end of 100 rounds (including zero'ing) I was pretty consistently hitting IPSC head "A" zone with two shots from the holster in sub 3.5 seconds at 10 yards. Not "Black Belt" performance but encouraging.
Literally when I got back from that range trip, found a Holosun SCS for my G19 in the mailbox. Got it mounted up but haven't had the ability to zero yet. While I'm a big fan of Holosuns in general, the comparison of dot clarity to the SRO is horrifying. On the "dot only" I've got a green amoeba that's vaguely oblong, with tons of bloom, even with the sensors covered to get the dot dimmed down.
After shooting the 5MOA SRO, I'm not sure what I was thinking when I thought the HS "circle dot" would be a good idea...
More to follow after I get the G19 out to get the SCS zero'd.
