Given a choice between the two, I'd take the GSG. Had a really hard time not bringing home the first one I handled. Still might. The G22 was cut out right and sewn up wrong or something. It could definitely stand some design tweaking.
I held a GSG last week, shop was asking $499 it just seemed high for how it was made. Tons of plastic. I think if they were closer to $300 I would pick one up.
I already have a 10/22 with 30 rds and a folder. I have about $250 in my set up I can't see why GSG's are so expensive????
