I am considering WASA for my CAS choice. I bought a S&W M10 4" in 38 Special for a possible DA handgun choice. This would be a modern handgun with plenty of parts available. The first thing I noticed was the excellent (best?) blue on this M10. The trigger is serrated, hammer mounted firing pin, fixed sights with the front sight serrated and angled. I replaced the factory grips with a old walnut diamond with good checkering. It really resembles a S&W Model of 1899. I took this revolver to the range. I had a lot of trouble the first time out. I could not fire a fast double action string. I was outrunning the lockwork. The M10 was fine in single action, aimed fire. When I tried to dump the cylinder fast, lock-up! I took the revolver back home and decided to tear it down. I did just that. I didn't find anything unusual. ? I put the revolver back together and polished everything as I went. I dryfired the little M10 while watching DVDs this weekend. I have achieved success! I put 102 rounds through this revolver as fast as I could load, fire, dump and reload and fire again. No hitches. I can work on a 158 gr lead bullet cartridge choice now. I like this S&W M10 for what it is. A truly American icon that is deserving of its worldwide acclaim and reputation. They aren't hand made anymore but, they respond well to a little human TLC. CAS and double action can coexist easily. The S&W M10 is an affordable stand-in for the Model of 1899. I did feel "funny" in loading 1-at-a-time. I have been reliant on speedloaders for too long. I haven't given up on single action shooting, I do enjoy this type of CAS though. Think The Professionals.
