Barami update
Got my barami in the mail yesterday just about 15 minutes before heading out the door to the range, so I've had a chance to both carry and shoot it a little bit.
Short review: I like the way it feels a lot. It puts my 340 in much easier-to-access position than pocket carry, yet is totally discrete with the simplest cover (any untucked shirt). I'm carrying at 3:30-4:00, and it's perfectly comfortable to sit, drive, walk, whatever.
I'm not so crazy about the way it looks. It's chintzy black plastic, and I had to remove an attractive pair of wood combat grips that I bought from S&W, then shaped to my own preference and oiled.
Nor am I entirely crazy about shooting with it. Don't get me wrong; it did not impede control or accuracy, using 38 +p ammo in my little 12 oz. snub. I shot a box of 50 and got only a small blister on my thumb; but I've gotten to where, using other grips, I can shoot a couple of boxes with no such problems and no discomfort to speak of.
So, barami is a very workable option that is very good at what it's good at: discrete, easy carry. I'm going to run with it for a while, and suspect my other grips will be relegated to times when I'm showing off my ultralite wonder at the range or expecting to use other modes of carry (pocket or bellybag) for a while for whatever reason.
MikeJ--I don't know how much of an effect the extra 10 or so ounces of your gun would have. I think with the right pants and belt, you'd be fine. With my gun, I've been carrying in pretty light shorts all day without any slippage. The 640 is a great weapon; hope you enjoy it.
