I have been carrying a Kimber Ultra II Stainless model or an ATI Fatboy for my EDC for about 2 years or so and just this weekend picked up a used New Agent. I really, really, really like the New Agent.
After putting 200 rounds through the New Agent without lubing her(torture test kind of thing) as well as a couple hundred rounds through her after lubing, I can safely say the thing is a reliable little package. Surprisingly/not surprisingly the fitting of the slide to frame is actually "quite" loose but this is probably an 08 gun so I think the craftsmanship at Colt was a little laxxed around then, the roll marks are somewhat rough as well. That being said I could care less about an EDC piece that will probably get beat to piss any ways. Out of all 3 pistols, my ATI actually is the tightest of the three as far as frame to slide fit goes, go figure. The New Agent did come with Crimson Trace lazer grips but I ditched those in favor of some other thin grips I had already. Everyone who shot my New Agent (5-6 people) did mention that the gun seemed to shoot a little lower than where you pointed but was still very Minute of Bad Guy.
We were all shooting from about 15-25 yards away from our targets.
The final surprise and probably the best of all was what I found out after putting it in my holster/carrying the thing around all day. I barely realized the gun was there and it was not due to lack of weight(although I would have to say this is probably the lightest of the 3 micro 1911's I have). For some reason my other two pistols would "jab" me in the side if I would lean too far over to the side that I carry my pistol on(around the 3 o' clock position), especially while sitting/driving in my truck. This I now realize is because of the extended beaver tail grip safety's on them, with this Colt New Agent I initially carried the gun from 8 a.m.-10 p.m. and did not feel any sort of uncomfortably what so ever and more importantly, no more jabs to the side or trying to sit in a position so as to not put pressure on my carry side. The lack of extended beaver tail safety on this Colt is making me rethink having extended beaver tail safety's on my other carry 1911's.
Overall I am super happy with the New Agent thus far and can only hope it will stay a nice and reliable gun, which with proper maintenance and care I have no doubt it will.
ETA: I also agree with the above statement that you
NEED a proper gun belt as well as a proper holster to carry. I am using a Crossbread belt and holster, I say that not to advertise but to indicate that I know what a proper holster and belt are. Pretty much don't get the cheapest Amazon special you can find.
Also there is nothing wrong with carrying a full size 1911 for all the reasons stated in the post above. I have a friend who carries a full 5" Springfield IWB and has no problems what so ever.
