I agree with 475 but I would stiil opt for a peep sight over the leaf system.

The NECG rear peep for the Rugers is a very good unit. My only complaint with it is the blocky appearance. I'd like to see one 'melted', if you will. Still thinking about trying that myself.

Also, those NECG front beads for the Rugers are very nice and functional. It's hard to beat the combo of a high visibility front sight with a good adjustable rear peep.

Cheers.
