I have shot the 340 Pd. And two things......one the recoil pulled crimp on the bullets in the chambers and locked it up with full .357 loads........second......if you want know what it is like to shoot.....go out to your car an open the door and place your hand where the door meets the frame and slam it shut as hard as you can.......
I have shot full house .44 mag that felt tame compared to the 340 Pd.
If you had to pull the trigger on a bad guy...you might get two shots off....then you will want to let the bad guy shoot for a while so your hand can regain feeling.
