SERIOUSLY, you know nothing about glocks.... how many rounds have you put thru a glock ?? I shoot 5000-10,000 rounds thru a glock a year with no problem.... I just finished a 2 day fighting pistol course shooting 800 rounds of ammo and where 16 of the 21 shooters where shooting GLOCKS (the other guns where 2x S&W 5946/1x Taurus 1911/1x HK USP/1 CZ p-01) so during those 2 days that I was there at least 12,800 rounds where fired from glocks pistols without a hiccup..... then most of the guys stayed for the "advanced" course and the shotgun course which entailed another 1200 rounds each... and from what I hear all glocks made it thru without a hiccup.
I have been shooting glocks since 1995..... all shapes and sizes... 100's of thousands of rounds thru various models..... my current G17 has 25,000 rounds thru it and still looks new except for the holster wear on the nose... the only part I have changed is the recoil spring and the trigger spring every 10k
In other words, you are so in tune with the Glock operating system that you cannot fathom that an individual with less experience would have the slightest issue with one, even though his actions/reactions must be less intuitive than your own. The pistol you choose to shoot is totally irrelevant because that level of exposure to shooting should result in a very high degree of performance with anything. The fact that you've stuck with it for this long suggests you have achieved that very high level of performance, other wise you might have found a more fulfilling way to spend your time and money. Clearly, the Glock is the best pistol for you.
The vast majority of those who choose a pistol for self defense are probably not enthusiasts, competitors, or even LEOs. They won't fire a fraction of that ammo you do, even though they are basically familiar with their pistols and should be able to qualify on a LEO equivalent course of fire. It would be fair to say that they would be more likely be confounded by smaller problems than you are. They might do well to consider a pistol that operates more like their other firearms, that is with a safety and a more typical trigger system, regardless of the praise the enthusiasts heap on Glock.
The proper analogy might be the long haul trucker and the daily commuter. The commuter is concerned with getting from A to B along a single route in order to live his life, whereas road travel to the long haul trucker is his life. The commuter begins to feel anxious when exposed to traffic for more than 40 minutes, or when he must detour to an unfamiliar route. On the other hand the trucker begins to feel anxious after a few hours away from the cab of his rig.
Many people believe that shooting skills can be maintained by shooting 50 rounds or so per week, and that is probably correct if the individual's initial training has been adequate. After all, one does not need to drive 12,000 miles a month in order to pass a road test or operate a vehicle safely. While I have no idea of how many rounds I've fired from pistols and rifles since the mid 60's, I imagine if all of my brass could be put into a single pile it would cause a scrap dealer to salivate.
