My time with a 1911 when I was on a Pacific Regional Navy Rifle and Pistol team cured me of any ambition to ever own a 1911. We will not solve that fight here nor do I care to. If you have a reliable 1911 and that is your fighting sidearm, there are legions of blogs and books that will assuage and entertain that confirmation bias. 

Skip, our Village Armorer, has also been rocking the Glock nearly as long as me and has built several of the 80% Glock lower builds with terrific results. 

For the past handful of years, I've been training with my Glock pistols several days every week, firing up to 40,000 rounds a year through Glock pistols alone. Almost all of that has been with my carry gun, a Gen 4 Glock 19. Today I own several G19s and a couple of other Glock models. These constitute the entirety of my pistol collection; save for a couple of curiosities I've picked up over the years. All other pistols I sold because they held no purpose for me.

I did not start out owning and shooting Glocks, but I soon learned and amended the error of my ways. I'm not blind to other popular pistol models, however, as I have also spent the past few years putting a different pistol model through its paces every month in my capacity of writing firearms reviews for my local indoor gun range's blog. In doing so, I've put hundreds and even thousands of rounds each through Walthers, Sig Sauers, Caniks, Tauruses, Kimbers, Rugers, Springfields, Smith & Wessons, CZs, FNs, Colts, Brownings, Sphinxes, Hudsons, H&Ks, Remingtons, and likely others; in most cases, several models from each of these manufacturers.
