I carried a 9mm Dan Wesson Guardian on duty for 4 or 5 years. Took it through multiple 1,000+ round count instructor schools, 2 SWAT schools, etc., and it never missed a beat. Actually had two of them, the other I converted to .38 Super. I absolutely loved those guns. They ran great and were a ton of fun to shoot. They can be had for around $1300 or so.
I just spec'd out and ordered a Wilson 9mm Commander that I'm really looking forward to.
