Alright, after having done some research, I've settled on the RIA 1911 .22. I haven't liked the reports I've received from other guns like the GSG or the Colt/Umarex.
I did call them and ask about dry firing, and they confirmed that the gun does not get damaged when dry fired. Centerfire Systems also has magazines for this for $25 apiece. I also discovered that Armscor provides a lifetime warranty for their guns, and that their customer service is incredible.
I got my FOID card in yesterday, so I'll head over to a nearby range tomorrow and ask them a few questions, try out a few guns, and see if we can get one of these ordered.
