Forgot to mention...
22 LR pistols are just plain fun to shoot. If you’re at the range shooting a larger caliber pistol and you can’t seem to do anything right...pull out the 22 semi-auto. The world will return to perfect alignment.
I have a Ruger MkIII, 5.5” barrel. It’s a pain to clean, but it’s a hoot to shoot.
Also...there is a factory recall on some Ruger Mk IV’s right now.
My brother has Mark II. Fun to shoot and quite accurate. Huge PITA to reassemble after cleaning. Were it not for a youtube tutorial it would probably be sitting in pieces on the gun bench.
