As gra says the BB shooters have a lower build quality but i own both and it dont stop me buying the BB shooters haha..
If you can put up with not having blowback and not really them being true replicas, i HIGHLY recommend one of the umarex pellet shooters, S&W 686, Beretta 92fs, Colt 1911A1, Walther CP88, not so much the CP99 though its the roughest out the lot lol..
Out of all the guns in my collection though, the one i have most fun with and shoot the most is my sexy 1911 blowback BB shooter, customized by the man above..
All i will say is mate, dont rush into buying anything, find things you like the look of, then youtube the hell out of it hahaha..
Some of my favourite guns in. You collection, Umarex Beretta 92fs - Colt Custom 1911 - Walther Lever Action - TM Hi-Capa Custom Build Project - Colt SAA .45 & many more..
