i would love to, but i do not know how. especially with this back up computer. the good one bit the dust a month ago. we are gonna get it fixed, but don't know when. i got it at military gun supply in ft. worth. hk helped me get it. but if i can figure out how to do it..... i gotta tell you, this weapon shoots as good if not better than aGlock. it really does. my wife said all she could hear from the back 40 was something like a machine gun and a loud "woo-hoo!!!" i had ear plugs in so..... now repeat after me...." i need a CZ-82,i need a CZ-82....":wacko::wacko::wacko:
