You’re 100% right in appreciating the 1911 and it’s history. There’s no doubt that it was the right handgun at the right time.
I think the grip safety and the trigger are two of its biggest successes. However, I prefer the “modified Browning” (linkless) lockup of the SIGs and Glocks. It just seems to work better and makes the weapon much easier to disassemble and reassemble under dire circumstances.
If they every put as nice a trigger on a SIG or Glock, it would be the best of both worlds.
Concur on the lockup differences. A Glock can be detail stripped effortlessly and quickly.
DIY can make a huge difference on a Glock trigger and action. That I know for sure, without compromising function/safety. Sig trig? Don’t have one:-(
