By "decent quality pistol" I think we can assume he comes from the Walmart/Canadian Tire springer world... in which case it would constitute some kind of an upgrade, I guess.

To OP:

It is definitely too hot for the "odd game with friends" on property. Someone might get hurt and you don't want that.

As for the "other Misc things": As long as you're not shooting squirrels and birds... I guess that's right. Inhert target only please? Be responsible, this is a weapon, not a toy.

Wear eye protection, even when just target shooting -> BBs loves to bounce, a lot.

Make sure you DO NOT get seen with a pistol in public; ANY kind of public.
If living in a city or something, be extra cautious of that. A better advice would be don't use it outdoors in that case, because it's probably illegal anyways, according to your city's bylaws.

The reason we care about this? If you get in the news because cops got called on you and weapons were drawn, you'd contribute on ruining the sport for everyone (especially you, but everyone else too). So please, just make sure you're handling that thing responsibly!

Cheers
