I have many different handguns and calibers (except .40 Short & Weak), still say if I knew I was going to be in a gunfight my go to would be my battered old Government model 1911.45ACP and 1911's were the hand gun's of the boomer's parents and grandparents.
But I pre-date the boomer generation, so there’s that. The 1911 was relatively new technology, still waiting to win WW2 when I was born.
