I have a GSG 1911 22cal. it has been an accurate, reliable semi auto .22.
For the most part I have been happy with it, previously had a Walther 22 and it was a jamb-o-matic and the Sig mosquito was worse.
For many years had a Ruger MKII and it was a fine handgun.
One annoying thing about the GSG, when I holster it the slide spring is so weak, the holster causes a round to chamber, not a fault of the gun just an idiosyncrasy of the the design. I have to make sure the safety is on to lock the slide.
I believe CDNN has them on sale for around $225.00 and at that price they are a very good value.
