Yeah, I was going to suggest that you buy him a gun even before I read this. A lot of guys love guns. Drawbacks are that you don't like them, and statistically you're the one most likely to catch a round in a Pistorius/Steenkamp scenario. If he already has guns, you might please him with a high-quality accessory, like a holster for his pistol or a scope for his rifle. You could also buy him ammunition, which is essential and expensive. I'm precluded by an inconvenient diagnosis from purchasing firearms in my state, but I can buy all the ammunition I want. We give our neighbors gift baskets loaded with boxes of shotgun shells and bottles of bore cleaner at Christmastime. They never thank us, but I know that they appreciate the gesture.
