Aim got in some more 2nd gen G22 glocks. I'm thinking about picking one up since I like the smooth front strap of the 2nd gen, but I wasn't sure if buying a police trade in is a good idea. Would one of these gun be good to go or do I need to wait until I can afford a new glock?

Gun can be seen here.
