I recently added a GSG 1911 22lr to my roster, as did one other shooter at the gun club where I shoot every Tuesday morning. Last week, the bottom half of my friend's barrel bushing literally broke off after he'd been shooting for just a few mags. He lost a washer in the process and his gun is now out of commission. Today after a couple mags my GSG stopped cycling correctly. I changed mags, and the problems persisted, so I broke it down. Low and behold, my guide rod is literally gone and the guide spring is now doubled over in its place. It turns out the guide rod broke (rod broke off of the cylinder it's attached to) and was sent about 5 feet down range. Fortunately, I managed to recover all other pieces. So now mine is out of commission as well. That's 2-for-2 in my book. Both were cases where obviously suspect metal pieces were apparently too vulnerable to tolerate the massive power of the 22lr round. Both of us clean and assemble our guns competently, and between the two of us we don't have 1000 rounds through our GSGs. A little online research has made it clear that our problems are in fact common with this gun. I think this gun is a fine concept, but I wouldn't recommend anyone add one until GSG decides to improve the quality a bit. And if you already have one that you enjoy shooting, it might be a good idea to investigate opportunities to upgrade some of the weaker points in its function.
