"The UHP issued RMs? I wonder how many and where they all are now?"

Probably less than a hundred RM's, probably a lot less. The UHP was never a very big agency, I don't think they have 400 troopers even now.

All over the country. Saxon Pig has posted photos of his. I have never seen one for sale here, but I think he said he bought his when he lived in Utah some time ago. The R.M. replaced the 6-1/2 inch Second Model .44 Specials they first issued. I've got one of those.

I went through the state police academy with 3 UHP rookies in 1981. Their issued guns were all M-27 -somethings and were really worn, one being almost unsafe to shoot from almost no carry-up. He did his firearms training with his own Model 19.
