Oka y. The 1911 platform is 111 years old (1911-2022). It still works. It is still dependable. It may not be as cheap as some of the plastic pistols out there, and it uses a somewhat dated cartridge, the Colt .45cal ACP. So... I have a 1911 in 9mm. I have one in .38 Super. They all three shoot, and they are all quite accurate (remember, these are combat pistols, not target guns by design). Another invention, the wheel, is quite a bit older and we still use it and plan on using it into the future. So, old isn't a reason to abandon, it's just proof that the design is good and reliable.
(I just wish it wasn't so damn expensive...)
