Sorry for any confusion. Since you mentioned Dennis Ming, the context implied 'cowboy' to me. Also apologize for the mini-rant. It still rankles me, perhaps more than it should. Just because I found a bunch of poseurs at what I'd expected to be, at least nominally, a shooting match doesn't justify sweeping generalization.
Anyway, the "express" type of open sight with a shallow "Vee" rear and largish bead front should work very well on your carbine. After all, the concept proved itself admirably on the big double rifles for fast accurate placement at close-to-moderate ranges on some of the nastiest stuff our planet has raised. It should be just as efficient for fast shots at deer, hogs, black bear, or the like here. In an SD/HD role, I don't think even the vaunted 'ghost ring' is faster to pick up. I use them on a couple of my regular CCW handguns and like them a lot.
Greyrock: While traveling to Texas isn't economically feasible right now, I'm much obliged for the kind invitation. The idea of being able to compete with my C&B replicas in something a little more 'fun' than paper bullseyes still has a lot of appeal to the Walter Mitty in me. Just not to the extent where I'm willing to go to extremes in order to indulge it. FWIW, I'll do some looking around in the area to see if I can't find a place where the 'gamesmen' and the Fashion Nazis don't ruin the contest.
