I have decided that I need a reasonably priced .22LR target pistol. I have shot and enjoyed a Ruger 22-45, but never wanted to own one - complicated disassembly/re-assembly is not something I enjoy. Also, I have shot an older S&W Model 41, but they cost more than I want to spend. With the Mark IV and its supposed simpler maintenance, I am interested in acquiring the Ruger. The proprietor of my favorite local range told me to try the S&W SV22; he says if I do so, I will like it better than the Ruger and save money as well. Friday, I will go back and try his rentals of the SV22 and Mark III. Here are some questions: What do those of you who have shot these pistols think of them? How does the Mark III compare to the Mark IV in terms of accuracy, reliability and the fun-to-shoot factor. Any others I should consider? Thanks for your input. P.S. This assumes that someone has shot the Mark IV; I have just learned that they are hard to find as of yet.
