I will be purchasing my first two handguns shortly and have decided on a walther p22 or sig 1911 .22 for plinking. any other planking gun suggestions are welcome. The real question I would like some help with is whether to get a 17 or a 19? Does the 17 have sufficient stopping power? What generation is best? how much will good ammo run me? What other options do you suggest that will not give my wallet a heart attack? thanks everyone.
