I own an aged Ruger single 6 and a relatively new Neos for my wife, and she prefers the Ruger, because of the problems with the Neos, So both my wife and I prefer the wheel guns for dependability, at least for 22's. I have a M9 that has fired flawlessly for several hundred rounds, and my son's H&K 45 has had many rounds through it with no problems.
