~2.5 months after I started this thread I finally picked myself up a GP100 3 inch barrel from GrabAGun (Thanks for the link andrew1220). Purchased 6/20, shipped 6/23, picked up from Mass Firearms School 6/24 (painless transfer at MFS, the whole process was 20min, $25 transfer fee. Can't ask for anything more than that!)
I took it to the range today and put 100rds of 38spl down the pipe. Love it. This thing is a tank. The double action trigger has a bit of a hitch just before the hammer release which I like. It allows me to pull the trigger and hold right before the trigger break. VERY accurate out of the box. The front sight is black which makes it a little challenging to pick it up when sighting on a black target. Anyone have any experience changing a fixed sight? (I am also considering painting the tip of the sight with some bright paint. Anyone done this?) Overall I am thrilled with the purchase.
I am looking forward to finding some 357 (as this was the original reason for buying this pistol). Anyone got any leads on 357? I haven't been able to find any over the last 2 weeks or so (admittedly my search was limited to 3 stores).
Thanks everyone for the info in this thread. This is my first revolver and I can see another in my future very soon...
