The beauty of the modern world is that we have many more choices than we had "back in the day."
Which is your way of saying "I have an emotional attachment to an outdated weapon system and you're not going to take that away from me."?
That would apply to my wifey, but not to my firearms. That would be a most liberal statement to make, and emotion has no place here. What I am saying is that I weigh the pros and cons of any weapons system with as many factors as I can identify. Do I appreciate weapons systems of yore? Of course I do! To not appreciate that is to not fully appreciate what brought us to this point in weaponry, and possibly, beyond this point. I can appreciate a "Brown Bess" musket just as much as I appreciate an AR10 or a Barrett.
By the way, The Glock pistol design is about 35 years old. That is considered an antique, and in a matter of years, it could classify as a curio and relic. That's not bad record for someone who had no experience with firearms design or manufacture.
"Striker-fired" pistols are nothing "new." Heckler and Koch produced a pistol that was both plastic and striker fired in 1970, twelve years earlier than the Glock. And, "striker-fired" guns actually go back to around 1824 with the advent of bolt-action rifles. So, you can thank old rifles like the Mauser 98, Lee-Enfield, and Mosin-Nagant for the modern "Striker-fired" pistol, which is nothing more than releasing a firing pin that is under spring tension rather than beating it with a hammer, internal or otherwise.
