Another +1 on the finger grooves. The G21 grip is big enough without the grooves. It's not really a hindrance to using it, just a personal nit pick as I would be fine without it.
The new gun shop that opened here only offers a $200 credit for a traded in pistol. Even a still slightly used G21. So forget em', I was considering trading it for a new one, but am not going to take a beating on the trade.
Mine is fine, it's a big railroad tie, but I rely on its function, and count on it's performance. It's kinda weird, holding it feels too big, shooting it feels just right....
Hmmmmmm....
