Josh - You have to factor in that you are used to shooting a rocker style trigger, while the 1911 has a linear trigger.
I feel the linear trigger is a far superior design for putting rounds on target, but it's going to take some time to adapt your trigger pull from the longer take up and rocker motion of that of your revolvers or your Glocks, in comparison to the short travel and instant bang of a good 1911 trigger.
For your first time shooting the weapon, at 7 yards, with unfamiliar recoil and ammo just off the shelf, I don't think you did bad in any stretch of the imagination. All of those shots would be center mass of a bad guy - and that is all you are trying to do in a "Get it out and get it smoking" situation.
I am betting with a little practice you will see those groups tighten right up - and when you get used to the trigger, you will find that you are nailing a lot more of those shots exactly where you intended to put them.
Fine choice for a new sidearm - you have officially "crossed over" now and achieved a new level of consciousness about your handgun choices.
