I actually don’t find the Glock 21 to be too heavy and if I found myself in a gun fight, there’s no other handgun I would want to have in my hand and I can pretty much take my pick at this point. From under a T shirt, it comes out of the Aker flatsider extremely fast and even while dashing, the bullets go right where you want them at normal handgun combat distances. I have carried many different guns but I always end up going back to the Glock 21. It’s a true combat masterpiece IMO.
Oh geez. You couldn’t find a bigger gun??
I’m 52, had to display my gun once in 25 years of carrying to make some guy change his mind about his choice of victims and that was just a J-frame S&W. So, I carry a Beretta PX4 Storm Subcompact these days. 13 rounds of 9mm JHP will do the job.
