I shot Clark guns for many years and certainly have no complaints but do have a lot of praise for them. One of the best reasons to use Clark is that when you put enough rounds thru it so it needs to retightened and tuned back up, he will do it for $175 on pistols that he originally built.

If I didn't use Clark, I would use Dave Salyer. I've been shooting his pistols the last few years while I save the Clarks I have since Jim Sr. built them. The pistols Dave built for me are 2" guns and his prices are very reasonable.
