i do not have a .340 what i have is a 342 - only .38+P, but also lighter than the .340 by several ounces. the lightest revolver S&W has made as a production item.

i used to shoot the "FBI" load - a +P 158 LSWCHP's out of it with zero problems. and i have MS. 3 weeks ago i shot a hog with it using the fbi load and the 5 rounds were not bad in the least

i use a hogue monogrip. it is flush with the bottom of the frame (pinkie underneath) boot on all of my j frames.
