I have no experience with the Trojan 6.0 in .45 but I have lots of experience with 2 Trojan 5" in 9mm due to working at a rental range and my final answer is buy with confidence.
Keeping in mind that I have direct experience with these guns which are not abused but are not treated like safe queens and see thousands and thousands of rounds per week, I can say that for the same price, there may be equal 1911s but I highly doubt there are better ones. The other 1911s we have are .45s and are the Remington R1, a couple of SIGs, and an Iver Johnson. The Iver and Remington are about half the price but the SIGs are in the same price bracket and I can say with confidence that the STIs absolutely destroy the SIG when it comes to reliability and durability. This is not a bash on SIGs as it is more praise on STIs. Thousands of rounds per week and constantly being handled by first-time shooters is bound to take its toll on most any gun and our Glocks and STIs handle it the best. This is what I have seen with my own two eyes but our Trojans outlast everything except Glock. Yes, they outlast SIG 1911s and P22Xs, M&Ps, Beretta 92s, CZs, HKs, etc.
It is actually crazy considering 1911s are regarded as a platform which requires more end-user knowledge and regular maintenance and they are more finicky... and overall I believe this to be true so I'm not sure what is up with our STIs (2 Trojans and a Ranger II) but without any special attention, they just keep on trucking.
