To be safe, put it in a hard case, and lock the case. And make sure it is unloaded...and the ammo is stored in some other location. IL is not weapon friendly.
I despise having to travel across that state.
Mine is in my profile image. It's a S&W 1911 E Series Bobtail. Finest shooting gun i have ever shot. Bar none. it's been my daily carry for a long time, but i just picked up a SW MP 9c 2.0 that is now what I am carrying, bit smaller, lighter. More rounds.
Every time i go in, I manage to pick something up. Got my NAA 22 magnum derringer revolver there. Just picked up some 12 gauge 00 buck this past weekend, and some .410 000 buck for my son in law.
Well, i picked up an MP 9c 2.0 from 4Guns in Lafayette. They are great to work with. And i love the gun. Trigger is vastly improved. I love the tactile reset.
