Arthritis in my neck and shoulder has become bad enough so that shooting rifles is not a wise thing to do, so I’ve been shooting and buying more handguns. I have an old Ruger Standard that my father bought brand new in 1950 for $37.50. I field stripped it once a few years ago. What a nightmare. If it wasn’t for a YouTube video, I would never have figured out how to get it apart and no way could I have got it back together, and it took the patients of two of us to get it back together. There was 50 years plus of powder residue inside. Wish I’d taken a photo. I decided that I would never take that gun apart again, and have not even shot it since. I don’t shoot .22's much, but I see more of that in my future. Hence some interest in the MK IV. I decided on the Ruger Mark IV 22/45 Target, however I started looking at the Ruger Mark IV Lite, mostly because of the threaded barrel, tho I’ve never had any interest in Suppressors. I did discover that the Lite has a very thin barrel and that is a concern. A cool looking gun, but the thin barrel? Why they do that?
