It's fun! Well they both are quite fun. The S&W is light weight but more durable than I thought it would be. After about 500 rounds the S&W is proving to be much more ammo sensitive. It will not shoot Rem Golden Bullet bulk-pac at all. Many FTFs and FTEs per mag, Nor will it shoot Peters solids ...as out of the 50 I attempted to shoot (thankfully I only bought one box) about every other shot would fail to chamber. The American Eagle stuff chokes like Mama Cass on a ham sandwhich. It will shoot CCI mimi-mags, Federal bulk-pac, Blazer, Wolf, Federal Champion solids and any of the older .22 stuff I have around. Loading to 24 rounds per mag makes things better all around. The GSG, over 6000 rounds, will pretty much happily shoot anything without a hitch. The only ammo it had trouble with was American Eagle bulk.
