I'll take a cookie, and I'll share too.
Do you want a cookie for not liking Glocks?
I've literally owned and/or fired almost every brand name pistol out there, and when I consider pistols for carry (as opposed to buying for hunting or plinking) I prioritize the following items:
1) Reliability, either from personal experience or from recommendations from trusted friends.
2) Comfort and weight. Anything you decide not to carry because it pulls your pants down or has a burr on it that digs into you is a paperweight.
Then, way down the list, but still semi important:
3) Availabilty of quality holsters (I have purchased a couples of pistols I intended to carry and then couldn't find a decent holster for it. S&W PC 945 is a great pistol similar to 1911, but different enough that it doesn't sit securely in a 1911 holster. Had to get one made).
4) Availability of accessories I want. I prefer lasermax internal sites, and I almost always change springs, adjust trigger for comfort, install night sites (in case lasermax fails), etc. If a pistol is in adjustable without a major gun smithing bill I'm not interested.
5) Price. I'm not carrying a $5,000 race gun, nor will I trust my life with a $200 off brand hunk of junk.
You'll probably note that those criteria are very similar to how people pick a personal vehicle (other than holster), and just like Ford or Chevy or whatever brand people prefer, they fall into ruts from brand loyalty because "I've always carried/driven ____ and never had an issue so I stick with it." The problem is when they become "Gun Snobs" and look down on people who carry anything else. Truth is the vast majority of modern pistols made by name brand manufacturers are reliable, BUT, just like cars, there are lemons out there that don't work worth a crap, but if someone has a bad experience with one particular pistol type or car type, they always avoid it. Every single S&W semi auto (except performance center) I've ever picked up has a sloppy feeling trigger, lots of travel, and the tension during travel always feels like someone poured sand in the mechanism....to me. I still have a 4506 I plink with and after a bunch of rounds through it the trigger feels a lot smoother now, and since the trigger bugged me I had the internals cleaned up, DA pull lightened a bit and a travel stop put on the trigger. No problem. I'd probably carry it now if it had a higher capacity and lower weight.
I carried a 1911 Colt Defender from the time I first got my permit until I realized everyone in my age group at the time was carrying plastic guns. I made fun of them, they made fun of me, we all went on. My Colt was always irritating in the summer, rubbed against my waste uncomfortably because it was too hot to layer and keep concealed, and I always felt like I needed to clean or wipe it down whenever I'd sweat on it. My brother finally gave me his Glock 19 to try out on my own time, so I did. I HATED it, hated the trigger pull, hated how square and clunky it felt, hated the grip angle, and ultimately hated the idea of trusting my life with a piece of plastic instead of steel, but I holstered it on my belt line and was impressed at how comfortable it was (no burrs or protrusions digging into me) and how light it was. So I bought one (got some dirty looks at the store from the salesmen who all carried 1911s) AND I PRACTICED WITH IT. And I got used to how alien the trigger feels compared to a 1911. I still have the Defender, but of the four pistols I carry regularly, two are Glocks (an m20 and the 19 I bought 10 years ago). Wouldn't trade them for anything. The 20 I bought needed no adjustments at all, other than dropping in a lasermax (I ordered mine with factory night sites). No burrs, no rubs, etc.
Instead of hating on someone who is carrying a brand of pistol you dislike for whatever reason, you should shake their hand as a fellow gun owner/carrier and strike up a non confrontational conversation with them about their choice of weapon. Ultimately you probably have more in common with them than you think.
Incidentally, anyone who carries a Glock because they hope people will think they're a cop....has a big hill to climb with me to earn my trust. In my opinion that's a pretty poor excuse to carry.
