Scandium frame S&W .357. The thing seems to weigh about a pound. The grip is so small you are basically shooting one handed. It gives you a health punch in the palm, but worse is the trigger guard. Because you can't get a decent grip on it, the recoil throws the gun up and the trigger guard hits your finger.
Its doable, but its the point where, "this ain't fun anymore".
Other range notes:
-Shot an XD side by side with my Sig 226R (both .40). Its a nice gun, but the trigger is not as smooth as I would like. I generally dislike poly fram guns, and this did not change that.
-Shot a compact XD (.40). Nice. Damn accurate given the small furniture and short barrel. A bit fat for concealed carry.
-S&W 686 .357. I'm buying one. End of story. What a great revolver.
Best of the day?
Kimber Classic Custom. WOW. This thing was so accurate it was just insane. I fired an entire box through one target and ended up with a nice round hold about 3' around in the middle of the target.
