I have owned multiple Colt Diamondbacks 22"s 2.5", 4", and 6". As well, I have owned Model 18"s and 17's. and 617. The narrow trigger and the trigger stacking in double action were a turn off for me on the Colts.. The Smith's with our without wider target trigger had a far better double action trigger pull. Other then the 2.5" diamondback with smaller grips, I found the Colts muzzle heavy and the grips sucked vs the smith's in longer barrel lengths with target grips. For me the solution was simple kept the Smith's sold/traded the colts. Jump forward to current day, I am working with Colt Kobra 22 and find it more pleasurable to shoot then my 617 no dash Smith. Trigger is great and gun is very accurate. Hope this helps just one mans opinion.
