Earlier this year I bought a 340PD.
It is snappy with 357's but not that bad with 38's.
Upon reading some research comments I was expecting way worse.
Have only shot it on two different occasions, both times maybe 20 rounds of combined 357 and 38, recoil was not an issue.
Sure I wouldn't want to shoot 20 rounds of 357 in a row but I didn't buy it for a casual plinker.
I have a vid I'll have to find and post.
