My Airweight model 37 curiously fits me with standard grips.I say curiously because it is about the only gun I own that doesn't wear custom grips.
I shoot 154gr SWC propelled by 3.8gr Titegroup.
I haven't chronoed it in the model 37 but in a 6'' .357 mag it clocks 898fps.If you apply the rule of thumb of aprox 25fps per inch,that puts it down to 775 to 800 fps(I try not to be over optomistic).
And the thing is not a bear to shoot.I guess I can have my cake and eat it too!
