Unpopular opinion:

There is nothing wrong with liking 1911's. It's a historically important firearm with nice lines, ergos, balance and a sweet sweet trigger. If you wanted a solid mag fed carry gun then either this or a Browning High Power were probably the only reasonable choices during the first half of the 20th century.

Likewise there is nothing wrong with 45 ACP. It's a low pressure round that is easy on guns and brass, easy to reload, has a satisfying recoil impulse, and is a solid service caliber. Prior to the invention of reliable hollow points, reliable double stack magazines, and NATO adoption of 9x19 creating overwhelming economy of scale it was at least arguably the best of the major service calibers.

Where the Fuddism comes into play is where you let these perfectly legitimate strengths run away with your brain. The reality is that the guy in the stall next to you with a hunnit' dolla' hi-point is as well armed as you are, is rocking a deeper magazine, probably experiences fewer feed problems, and can afford to put two thousand rounds down range with the cash he saved by buying a gun that was engineered with modern manufacturing in mind.
