As you've waded through the piles of comments from both pro and hate camps, you've discovered that there are both things to love and hate about the glock pistol.
I think I can give a BETTER appraisal of the current generation of glock pistol. Understand that I am a 1911 govt model man, I also own and carry the Gen 3 Glock model 22 in .40 S&W.
For a carry weapon, I find the following:
6000 rounds through this weapon, no feed failures or failure to fire incidents. Modular frame, not the easiest weapon to conceal but doable. I'm not overly concerned about dinging or scratching it, I see it as a "tool". (Unlike my govt. model in which I notice and scream if ANY scratch is evident as I consider it "My baby")
Reliable, lightweight, combat/duty/defense pistol. Drop it, run it over, piss down the barrel, whatever, it will function. SIMPLE nomenclature. Polymer frame is rugged and durable.
Easy to use zero learning curve, draw, point and POP. I can understand why departments all over the country use the glock. It's simplicity and durability are case after case proven. Plenty of dead badguys can attest to it's utility in the hands of it's user.
As a target pistol, I find it leaves MUCH to be desired. I can not get this pistol to perform accuracywise in comparasin to my 1911, this dissapoints me. However, since it's my "carry weapon" and I understand this, it's no longer an issue. When I want to shoot target for PERFORMANCE, I rely on the 1911.
Appearance: This is one UGLY pistol. But, I also understand that it was intended to be "Business" -v- a work of art.
Safety issues: If you carry this pistol with good leather or a fobus holster and excersize proper trigger diciplen, AD is not an issue. Understand that when you jerk that puppy out of the holster and your finger is ON the trigger, it is READY to fire, don't look for an external safety to disengage, there is none. In many circles, this is an issue for many.
It is NOT the "fragmentation grenade" many bullshit artests try to slip in on the unaware. Yes, there have been bonified KABOOMS, but, no-more-so than any other handgun.
Tactical, once you get use to the ergonomics, it's point and shoot with quick target aquisition in the hands of a shooter who KNOWS what they are doing. The STOCK sights BLOW GOATS IMHO. (Think aftermarket, TRITIUM, it is a CARRY WEAPON)
Cleaning: This is a NO BRAINER... Little else could be easier. This pistol takes down with simplicity.
Additional: S&W and Springfield Armory XD pistols try to DUPLICATE the glock design and both with success, there's much to be said. I must say, SA's XD pistol IMHO is a fantastic improvement on the glock design.
Calibers: MANY! What's your flavor?
Assessories: Too many, and most offer little more than a new gadget that offers little if any REAL tactical advantage.
Overall: As I said above, this is a "tool" or a "duty weapon" as it were. It's not meant to be pretty nor is it meant to be a tack driver. Although, with custom barrels, (that command top dollar) there are COMPETITIVE shooters who take this pistol to their meets and walk away with both CASH and TROPHY. (Of which I have NEVER done or tried to do, I'm way out of my league against such shooters anyway). It's tough, dependable (Goes bang when you need it to), and not overly expensive. A plenty smart design for this tupperware pistol.
Push comes to shove: If the powers that be told me I had to choose between ONE pistol for the rest of my life, I'd take up the 1911 and dump the glock for the rest of my life and never look back. BUT.... understand, it's MY personal preference. I know guys who swear by their glocks who would just as quickly abandon the 1911. Could I trust my life to the glock pistol? That's easy, I already do. That should say something about Glock.
Are glocks any good? Absolutely. What you should be asking yourself is: "Is a GLOCK anygood for ME", screw what anyone else says, you'll be the one carrying it. Unless it's more of a department mandated purchase, you must make that decision on your own. I suggest you go to a range where Glock pistols are RENTED and shoot some before comitting to buying so you can decide for yourself.
FOOTNOTE: I am a former glock HATER. After years of turning my nose at these ugly plastic pistols, I gave them a "try", it performed and I bought one. Also, keep in mind that I am STILL a 1911 guy and the 1911 will remain my first love pistol.
