...you do not need to pull the triggeer in ANY of my Smith & Wesson, Beretta, Ruger, or Dan Wesson, semi-auto pistols...
At least two of the companies you listed make at least one pistol model that requires the trigger to be pulled for disassembly.
While that may or may not be a problem, it's certainly not a "Glock" problem since there were pistols for many years before Glocks were even thought of that required a trigger pull for disassembly.
It's a very rare ND that can be blamed on equipment though it's common for people to try. NDs are almost invariably the result of violating very simple safety rules.
