I absolutely love mine. I have put a few thousand rounds thru mine (just over 3,000). It feels super good in my hand and I feel very comfortable with it.
The only thing I do not like is the extended safety, I have no issues with it when shooting. When I carry the pistol (IWB, Comptac holster) I have to be extremely careful when removing the holster from my pants as it is very easy at that time for the safety to get disengaged. I am aware of the issue and typically place a finger inside to make sure the safety stays engaged when removing the holster and I have no issue. I do not have this issue on 1911's that do not have the extended safety so I think the extended safety is the problem.
FYI there is no issue or problem when removing the weapon from the holster only when removing the holster and pistol as a unit from my pants.
