OK fellows, I have been looking at the 340 models (M&P and PD models) and there is really only about $100.00 difference in them if I buy a new one via prices on GB. Now that I have the 442, I still want a 340 model since I am really liking the darker color with picking up the sight quicker but the big dot would be even better for me on the M&P. I am trying to figure out which would be best. I really like the M&P model because it already comes with the front night sight and is really the same weight as a standard 442 meaning it would shoot basically the same as my standard gun. The PD model is lighter in weight and I would then have to put on a night sight to get it like the M&P which would cost me more money. I am leaning towards the M&P model with NO lock. I just cannot find one around my neck of the woods to try out or inspect. This gun buying thing is a sickness, I mean really. Places just done stock the really good stuff as I hate hate hate buying through the mail.... GRRRRRR
I would probably opt for the 340 M&P in your case. I bought a couple when they first came out with no lock, but found I really disliked the big dot night sight. I also had some concerns(legitimate or not) about the durabilty of the two-piece barrel, since it seemed rather fragile and I've come across a few reports of the shrouds coming loose, but the sight was my biggest complaint. If they were to come out with a ramp sight version at a reasonable price, I might give them another look.
