Old technology? Consider that the 1911 design is based upon a modular concept. Doesn't sound so old to me. I wouldn't put words or deeds into Mr. Browning's mouth, but from what I can see, the pistol is designed to be able to change parts as they wear. Man made stuff does that. Some scoff at the barrel bushing setup, but I have a pre-enhanced series 80 that I am desperately trying to wear out, but so far I have succeeded in wearing out 4 barrel bushings in 80,000 rounds. If I had taken the second $10 bushing and hand fitted it, I probably could have gone a longer distance-we'll see. I fitted the 4th bushing by hand. Does anyone sell quality barrels or slides for $10 a throw? I haven't found them but would be interested!
Convenience? Not a bewildering number of parts, but something I can detail strip and reassemble in minutes, that with a Series 80.
Pounding tent pegs? How does a Glock hold up? Never tried it but did one time with my steel pot and the DI chewed me for denting it
There are those who make the 1911 design in double stack, plastic, aluminum, and compact if that makes an advantage for the individual. Most of the other designs copy or are modifications of the dropping barrel Browning design, so the crowing of SIG's and whatnot confirms, IMO the correctness of JMB's invention with Beretta locking block being the obvious exception. Sure, some of them have DA, DAO or Idon'tknow, but if "modern" technology is so needed, where is it? All I see is trigger controls and safeties on the new pistols.
Safety is a training issue, not just a function of controls.
