Welcome to the site!
In an urban environment, it's good to lock it in the glovebox, trunk or lockbox...which can be had for very little these days. I rarely do but I'm not around a lot of people.
I shoot cast RNFP's or Keith style in the revolvers... in everything but the Glock. It has to have a jacket bullet. I want penetration not expansion which IMO is problematic at best.
