Though he remains quiet and reclusive in nearly all other situations, local resident Frank Collins really brightens up and comes into his own when he visits Larrys Guns & Ammo in downtown Jackson, relatives of the 22-year-old reported Tuesday. He wont say three words to you all day, but once he steps into that gun shop hes like a flower blooming in spring, said Collins father Paul, explaining that in the store his son will immediately start pointing around and saying Ill take one of those, two of those, and how much is it for 1,000 rounds of ammunition? Hes always full of questions about reload times, stopping power, magazine capacitiesyou name it. Youd never believe he was the same kid who spends all weekend indoors with his blinds drawn. Going there seems to be really healthy for him. Gun store employees confirmed Collins suddenly grows distant and withdrawn when they take a few minutes to perform his federally mandated background check, but always perks right back up again the moment his purchase is approved.
