I've only had my SD RDS sight base fit one slide properly (i.e. no slop or wiggle) so far.

It's not too bad for acquiring a sight picture...and following up for doubles or triples. But it does take some getting used to since the dot seems to "jump" around. It also seems to float in "nothing-ness", in that there aren't any reference points to line things up. With a RDS on a rifle, the 3rd contact point is the stock in your shoulder...no such thing with a pistol and it takes quite a bit of getting used to.

Put it this way...I've tried the SD base/docter sight out on three builds...and now it's sitting in the parts bin.

If I put optics on my pistol...I'm going for a side mount with an integrated aimpoint ring. I'm struggling with putting optics on at all...95+% of the time I don't even remember looking at my iron sights, and then there's the long/aimed shots where the comfort/familiarity of iron sights (fiber optic fronts) is really nice. Optics are probably going to f*ck me up for a while until I adjust.
