Taurus 709 slim... Couldn't stop shooting low and left with that bugger. I know it was my trigger squeeze- but dang it I just could never get the hang of that pistol. Ended up trading it in on a Taurus M856 .38 Special with a wolf spring kit and I am very happy with what I can do at the 15 foot line firing double action. I need to have the front ramp milled and painted so I can focus better though. My wife's S&W 637 Airweight is also a really good shooter- the trigger is much better than my Taurus 856 and I can actually consistently hit a 10" steel plate at 25yds with it on single action.

Funny enough, I saw someone posted they like the M9... I'm in the military and I hate that thing. I can never qualify expert with it and it just feels wrong in my hands. If it has to be a semi-auto, I prefer a Glock to tell you the truth. Otherwise I am a real big fan of wheelguns.
