People are talking about how heavy the SP-101's are...
I just feel Ruger builds one hell of a revolver! It is a gun that just by picking it up, you know it's not going to let you down!
My wife and I each have 2" SP-101's and about 8 or so years ago I was lucky to pick up a used Stainless Ruger Speed-Six w/ 3" barrel and Hogue Combat grips for around $180. ( I was freaking to get a Stainless .357 in a 3" for under $200. Came from U.S. Postal Inspectors when they switched over to the Baretta 92's, but those old Rugers were in primo condition! Like new!)
Now I have to say that 3" Speed-Six is just a natural companion to the SP-101 and I have no problems with either of them. I don't think they are too heavy... I think they are just right. To me, they feel like "security!"
If you pick up a 3" Smith or Ruger I think you'll be more than happy!
And then there are the Colt's too! Can't remember if they make a Python in 3" but if not, I bet you can find a gunsmith who can make it a 3" for ya!
