mugsie: As sterling jumped in, that is spot on what I ment. The PT1911 will not let you down; it is a good gun. Its accuracy will be equal to or slightly better than most service grade guns (Beretta 92, Glock, XD, M&P, etc.), but it won't have such things as "Guaranteed to shoot 2.5" or better at 50 yard or your money back" guarantee that a 2.5-4K 1911 might have attached. It may also lack some of the polish that an expensive 1911 has such as a custom fitted trigger, polished internal parts, etc. It will instead just work, might have a hair of grit, the trigger might not be exactly like glass breaking, just really close, etc. Slight imperfections that unless you know what to look for, you won't really notice. All of which cost a pritty penny to expunge. As others have stated, you might also find some machine marks on the insides the PT1911 that in an expensive 1911 would have been polished away.
Will any of these affect the operation of the gun in any way? None what so ever! But, getting rid of those marks, and adding that extra bit of polish costs money, and the law of diminishing returns also rears its ugly head at some point.
Overall, the PT1911 is a definite "BUY" gun in my view. But, it is a service grade weapon, that cannot be realistically expected to meet or exceed that maximum mechanical absolute performance of a custom-fitted match grade weapon costing 5-8 as much.
Like ghoster said, for 95% of shooters, there will be no difference between the PT1911 and a custom 2.5k 1911 in terms of performance. Only 5% who are dedicated, or have a mechanical rest to lock the gun into will be able to tell a difference between the two.
