I groused about the slide to frame fit on my 3 - 4 month old Eagle 40. I've now put about 3000 rounds through it and it just runs well and shoots straight and keeps running when fairly dirty (ran it for 400 rounds without cleaning with no issues, more than that would make me crazy), so I'm now really wondering if a tighter fit would make for a less reliable gun. In other words I'm wondering if for a competition gun the folks that fit things new what they were doing.
The factory trigger was way bad and I don't think there is any excuse for that though, weight was not that bad but creep was very bad and inconsistent, this was fixed quick and for a very reasonable price by my local gun smith but it is something that should not be required on any decent 1911 - 2011.
My back up gun is a Fusion (or it will be if they ever send it back from repair). It is more cosmetically appealing than the STI and fit tighter, but it breaks (or broke, assuming it comes home fixed) barrel link pins every 1500 rounds or so (just enough so you never could trust it at a match) and Fusion didn't know to do things like dimple around the rear sight pin pivot hole, so parts tend to come out while shooting (STI, Les Baer, etc all know to do this). After a certain amount of use the cosmetics are what they are for a competition gun for many of us.
My Les Baer seems to have everything (form and function out of the box). It started life a lot tighter but it is a 45 (less persnickety than 9's or 40's in my limited experience) and it took a few hundred rounds before it seemed free of the infrequent ftf. I'm not sure that comparing a well built 45 to a well built 9 or 40 is apples and apples, I do know that LB does not seem anxious to go away from 45 and my friend with an LB 9 seems to only have about average reliability.
