Long post/rant. Continue at your own risk.
I read this whole thread and it was a tough read. Lot's of opinions touted as facts. Well since we're throwing around opinions masqueraded as facts here's my two cents. First of all, congrats to
@steve white on his new CZ. Excellent choice. A modern reliable pistol in an adequate caliber.
My opinion #1. Revolvers most certainly do jam. It doesn't take much crud and junk to clog up the mechanism. Despite conventional wisdom the reality is a modern double action revolver has more moving parts than a typical modern semiauto pistol. They do break and they do malfunction. I've owned enough over the years to know this first hand.
My opinion #2. Glocks can and do malfunction. I've owned a bunch of them and still have a few. Excellent firearms but they're just as prone to malfunction as any other modern firearm. Yes, they're extremely reliable and I'd trust my life to one but they are NOT indestructible and 100% reliable as some would have you believe. The fact is most modern plastic fantastics are the equal of Glocks in almost every way. Glock set the standard but they aren't alone at the top of the heap anymore.
My opinion #3.1911's have been defending people and winning wars for 111 years. The 1911's that are problematic are usually cheap imitations built offshore or they're being limp wristed. Condemning all 1911's because your Philippine built $300 knockoff isn't reliable is like condemning all plastic fantastics because a KelTec wasn't reliable. Having said that almost all of us can anecdotally tell of a brand name 1911 that had problems. So what? A brief search of the interweb will yield the same results with just about every brand/model gun ever made. Including the almighty Glock.
My opinion #4. About 3 or 4 generations of men were first introduced to handguns via the M1911. Somehow they managed to get past the incredible recoil of 45ACP and the absurdly intricate manual of arms necessary to effective employ the pistol. It appears these two obstacles are vastly too difficult for the modern low-T millennial to overcome.
My opinion #5. People discuss handgun accuracy in a defensive/combat pistol like it matters. It doesn't. A 1" group at 25 yards with a match grade centerfire target pistol is phenomenally good and people pay a LOT of money to get that kind of result. Let's say for the sake of discussion an off the rack production pistol of any flavor can only achieve a 10" group at 25 yards. Most will do a lot better than that but stay with me for a minute. The math tells us that at 5 yards the difference between the two is less than 2 inches. A 1/5 inch group (actually at least a .357/356 group if they're all in the same hole, but you get the idea) vs a 2 inch group to be precise. At 2-3 yards, the real distance of most SD shootings, the difference in 'accuracy' is even more irrelevant. I'll say it again, unless you're involved in bullseye competition or handgun hunting, handgun accuracy for all intents and purposes means nothing. All modern handguns are way more accurate than necessary for most purposes. Even the cheap ones.
My opinion #6. Brand X guns aim too high, or too low, or whatever other excuse you need to justify why you can't hit what you're aiming at. Guns don't aim at all. Humans do. Adjust accordingly. It's not that hard. Also, back to My Opinion #5, in a SD situation it doesn't matter. If you're aiming center mass +/- a few inches doesn't matter. Dead is dead whether you hit the upper ventricle or the lower one. If you didn't hit the ventricle that's on you.
My opinion #7: Trigger this, trigger that. If any of you are harboring fantasies of trigger control during an SD situation you're not being honest with yourself. Yes, training, repetition and muscle memory matters. A lot. However, in all likelihood you're still gonna be jerking the trigger no matter how much money you spent to get the perfect 3lb no creep breaks like glass trigger. An experienced shooter may be jerking it less than a new shooter but perfect trigger control when your life is in immediate danger is a fantasy.
My opinion #8. What government agencies use (military and LEO) doesn't carry much weight with me. A particular group may choose a certain weapon but almost all the time money was a consideration and certain brands (Glock) subsidize the hell out their products to get the Gubmint to use them. That doesn't mean their choices aren't quality weapons but it does mean that functionality wasn't the only criteria. Plus, I've been around the government for long enough to know that kickbacks and corruption are part and parcel of the Swamp. Glocks are a great choice for the high speed low drag warriors but so are a lot of other very similar weapons. I absolutely promise you their selection of the Glock wasn't 100% based on merit and merit alone. That's not how the Feds work.
FTR, my opinions are based on 50 years of handgun ownership and many, many thousands of rounds. I've also owned well over 100 handguns in almost every caliber and configuration discussed in this thread. I still own more than my fair share. I've also competed (and won) with revolvers and semi autos (bullseye and speed events). I'm also a firearms instructor (rifle and pistol). So what. These are only my opinions based on my experience. YMMV.
