So a few years ago I bought a Glock 44 for a quick review; the intent was to shoot it and sell it. Turns out, I love that gun. At 10-15k rounds (I lost count), it has held up well. I still think that it hits a few inches low, but I haven't gotten around to calling customer service.
Anyhow, the gun is dead reliable. After about 1000 rounds with no cleaning, I might have some failures to extract or feed, but that's mostly ammo related. It definitely prefers to be a clean gun. Even so, it doesn't have to be pristine and it will keep eating ammo for a long time, just like a 9mm Glock.
My shooting skills have improved tremendously now that I can shoot 300-1000 rounds a session for very cheap. I do this usually every weekend in the summer, less in the colder months. It is an excellent training platform and the recoil is enough, thanks to the lightweight polymer hybrid slide, to have to keep a proper sight picture, just like on a full-size cartridge. People tout dry fire but I tout combat style .22 pistols.
My armorer/rangemaster buddy and his wife love the gun. It's fun to shoot. The 10 round mags suck and the Promag 18 rounders suck more (the loading tools 3D printers sell online help), but just buy like 10 or more magazines so you can load while the gun cools down and shoot a long string.
Up next is a Sig P322 with a red dot sight, to learn that system on the cheap. I see the point of pistol dots, but I'm not convinced they're for me. I'll review that gun and put a few thousand rounds through it and see how I feel about them after. Not sure I'll keep that gun, but we'll do a long term (like six month) test on it and see.
All in all, I would never have bought a .22 pistol, especially the Glock 44, if it wasn't something I could review, but I'm very glad that I did. Whatever your platform of choice is, I recommend getting the .22 equivalent to train realistically very cheaply and have fun at the same time.
