I own a couple of them.
After completing my first Glock armorer class I decided I might as well own one as an armorer and instructor (which I often use to justify the purchase of new firearm after attending an armorer class
). I ended up with a couple of them only because I had the chance to pick up a second one, which was LNIB, at a very attractive price not likely to come my way again. The price was just too good to let pass by, so to speak.
By my estimate I'm just now approaching having fired 10,000 rounds through each of my personally-owned Glocks.
I've attended a total of 7 armorer classes for a mix of 4 different designs of polymer-framed pistols over the years, so less than half of my armorer classes have involved polymer-framed pistols.
To date only 2 of those classes were for Glock. Probably enough to maintain a passing familiarity with them, though. I'm thinking I'll probably take at least one more recert class for a couple of the platforms, including Glock.
In addition I've worked with a fair number of folks who own and carry Glocks, which has involved everything from helping teach proper shooting techniques suited to obtaining good function from them to identifying gun-related problems and making repairs to their Glocks.
Glocks are fine pistols for their intended usage. I do, however, happen to find some number of features of a couple of the other maker's offerings worthy of respect and feel further refinements and improvements have occurred in the polymer pistol field since Glock became well established in this field.
As an armorer I think they're relatively easy to maintain, support and repair.
I think that many owners/users find it a challenge to use a proper grip/locked wrist shooting technique to optimize functioning.
I also have the personal opinion that Glocks are arguably at their best when chambered in 9mm.
I will readily admit a personal preference for traditional double action pistols for common defensive purpose as I've used them for a couple of decades for service use.
I also happen to like a nicely done 1911-style pistol and own several of them. I've carried a number of them as off-duty weapons over the course of my career, although I did turn down an offer to be issued one of a very few available full-size 1911's as a service weapon toward the end of my career. (I was more interested in carrying a lightweight compact alloy duty weapon in my plainclothes assignment.
)
I have many years experience with revolvers and appreciate single action, double action and double action only variants.
So, Glocks make up a very small, but useful, part of my personal handgun collection, overall.
I don't have any immediate plans to buy any more of them, though.
