These are popular and hard to find guns, the Ruger Speed Six in 9mm caliber. Stainless revolver with the 2.75" barrel, model GS92. This one is from the tail end of normal production with the rounded recoil shield. The SN is in the 158 prefix and shortly after this, around the 158-12xxx range, Ruger started changing to the scalloped shield design. There are no moonclips with this gun, but you can still find those online from 3rd party makers, and sometimes NOS on eBay or GunBroker (or even right here in the Classifieds with a WTB post). No box or papers.
