thanks guys, I did some searching after I posted this, and found the gunsmith section, where both of you posted about the 10-8 sight. I like the looks of it addition to what it makes you focus on. I am setting my MP40 up strictly as a combat gun, so I ordered a sight, I already have night sights on the gun, so with a black rear I think this will be a perfect setup. I also ordered a new 19lb recoil spring and guide rod from Wolf, maybe that will dampen down the recoil some more. I have noticed that after a few rounds I have to readjust my grip, probably because I am used to steel frames, this is my first polymer 40 since 1996 when I had a glock 23. I will say I am impressed with the gun so far, but it does need a little tweaking for my tastes. Thanks for the info.
James
