Superb gun. I've owned one for just over a month now, with about a thousand rounds through it. (It was my first pistol. I got excited.) Not a single malfunction. I do meticulously clean it though.
After trying all sorts of things, even asking some questions around here, I thought it was just right in every way. It's super comfortable, just the right size to fit my big hands but not be too big to carry, and shoots like a champ. Trigger is great (I've personally never noticed the groove) and the recoil is quite light. Bulls-eye's right out of the box. All I did was put the big set of grip panels on it.
Here in gun-unfriendly Mass, it was practically unobtainium, so I ended up paying absolutely top-dollar for it, but you know, I still think it was totally worth it. In that vein, yeah, mags are also super pricey. I only have three, and they all have silver lines running up them now since I can't cycle them out more often.
But yeah, totally epic.
