Like many, my initial introduction to GLOCK was through the media, discussing the "Glock 7" that would go through x-ray machines undetected. At the time, I'd been carrying a Sig P226, because that's what the SEALs carried - it had to be good! But, at the same time, I was finding the P226 to be heavy, and prone to rust (I was living/carrying in WA state at the time). A fellow Infantry officer brought his "toy gun" (G17) to one of our range dates, and I was pleasantly surprised with the capacity, weight, and general shootability. When, in 1998, the LGS that ate a huge chunk of my take home pay got G19s, I bought one of the first one in the state, and started carrying/shooting it.
But, I wasn't ready to go whole hog. The trigger sucked (compared to the Sigs, Berettas, and 1911s I was used to). It "felt" cheap, and "pointed wrong." It couldn't compare in shootability and accuracy to the 1911s I was inclined towards at the time. I sold the G19, bought a series of other pistols, looking for "the one;" but always ended up back with that pesky G19. I was eventually "issued my first divorce" and transferred to AZ, toting a Colt 1911 the whole trip. Once I got down there, I got into competition shooting at the local level in a BIG way - and IMMEDIATELY found out that my beloved Colt wouldn't feed FMJ reliably when introduced to the tiniest amount of grit, and that loading 7-round magazines into a skinny magazine well sucked. Somehow I ended up with a G22 (because you know 9mm isn't enough to knock down steel), and I proceeded to shoot about 100K rounds, almost ALL hand-load lead flat points, through that pistol over the course of 18 months. And, since AZ was Open Carry only then, the size of the G22 didn't bother me.
Next was a move to TX, back in the bad old days before legal CCW, but when concealed carry while "traveling" was OK. The G22 was too big for that application, but the G23 was "just right," and we all KNEW the 9mm was a popgun for wussies, while the .40 S&W JHP was a tiny little model of Mjolnir. Right up until the day when I found out that hot handloads and early-model G23s don't mix - resulting in a destroyed magazine, a magazine release that flat disappeared, and a stingy-ouchy hand. Obvious fix - get the new HK USP.
THAT lasted about three months, at which point I traded the HK off on a P228, which I traded off in about a month for another G23. Which I happily carried for years, on legal CHLs, until I got out of the Army and into Federal LE. At which point the availability of FREE 9mm brought me back to the G19 (off duty only at my first "Sig only" agency, and later both on and off duty when Glocks became authorized and approved).
And now, here I am, 27 years later, with a Gen4 G19 on my hip, and STILL looking for the "next great gun" that will (unsuccessfully) turn my attention away from the ugly duckling that just flat WORKS.
I'd like to say I'm older and wiser, but, clearly, I'm just older...
