I picked up a RM01 from Cabelas last week with the intent of mounting it on a FNX-45 and recently came across the Sig P226 RX, which has the milled slide and comes with their Romeo MRD. I've mounted MRD and scopes on handguns which includes a Model 41 with an Ultradot and a Browning Buckmark with a Primary Arms miniature red dot.

I know S&W and Glock have models with that capability but know just about any handgun is capable if you can mount a picatinny rail or find a base the fits where the rear sight is located.

Anyone else running a MRD on their pistols? Novelty or practical?
