Colt makes good firearms, plain and simple. Anyone who argues with that just has something against Colt, probably because they did not like the price. I am not saying that you cannot get other firearms of the same quality for the same price or less than Colt, just that Colt firearms are good.
However, Colt is not innovative like so many of the other companies. They do not release new and unique products. They sell 1911s and ARs primarily. There are plenty of other manufacturers selling 1911s and ARs. The difference is that Colt's product line is so limited. Look at Ruger or S&W or CZ or SIG or just about all the other big names. They offer ARs, 1911s, pocket pistols, bolt-action rifles, pistol variants using rifle rounds which are great for SBRs, shotguns. It just seems like Colt says, "We are making 1911s and ARs and that's good enough" whereas the other manufacturers and consistently introducing new pistols, new designs, and flooding the market with new ideas and guns.
