RE: Is there a 22 mag pistol?
I had the Heritage in the combo ... the 22 mag cylinder never operated correctly, by the time I packed it up and sent it back it was well past the warranty (shame on me) and they said it could be fixed (also had a loose barrel) for about $20 more than i spent on it originally. I told them to forget it and send it back the way it was. I have since cranked the barrel in as tight as I could with a bit of loc-tite on it, and have relegated it to regular 22 lr only now.
I then purchased the Ruger Super Single-Six in 2003, when I turned 50 yrs old (my birthday present to ME!) and Ruger was celebrating it's 50th year of production for the Super Single-Six. I did not buy the anniversary model, but instead opted for the stainless model with the 6" barrel and the adjustable sights. The anniversary model came only with a barrel that was 4+" and blue only with no adjustments on the sights.
I couldn't be happier with this gun....and it tends to shoot the 22 Mag's better than the reg 22 lr's. Probably the ammo, but both rounds do just fine for my purposes.
The Ruger Super Single-Six is an extremely well made handgun.
