"I'm thinking about getting a 340PD for pocket carry as well. How do you like yours? I keep hearing that it pains people to think about shooting full-house .357's in it. What ammo do you carry in it?"
When I first bought my 340pd I put 20 rounds of S&B 357 mag 158 gr. through it. Tried to finish the box, and couldn't do it.
I've never felt the need to put 357's in it since.
I carry 125 gr. JHP +P's in mine, and figure on fast follow up shots.
No, fiber-optic sights gather light. I have one on mine and you can't see it in the dark.
Tru-glo has come out with a fiber-optic night sight, but I haven't seen one yet. I have sights for my Glock 20 on backorder.
