There is going to be some variation with any man made item...even from the best of them. IMO, Freedom Arms is an awesome company...although I only have 1 gun from them I have seen several of their products.
My personal gun is a FA model 1997 45 Colt...with fixed sights, a fluted cylinder, 5 1/2" barrel (crowned), a trigger job, marcata grips.
The gun locks up like a vice. It hasn't changed a bit. I tend to shoot hot loads and it handles them GREAT. Even pushing 270 grains down range at over 1200 fps (H110 powder) the guns recoil is very manageable and I can't see a bit of wear or "break in." It is still a VICE!...despite being the "lowly 1997 model."

The reason I am so pleased with mine is because this "bank vault" lockup isn't only when the hammer is back and/or when the trigger pulled...but even when the hammer is down and after the trigger is released (and the firing pin is retracted while the gun is at "rest") my gun still has absolutely no play in it. It simply doesn't get any better IMO. If there is some play in your though...I wouldn't worry about it. Call Freedom Arms up and ask one of their gunsmiths if there is a problem with what you can describe to them. They will listen to your concerns and will tell you if you need to have it checked out.
