You carry a firearm in your pump?

have the small chipping hammer. reality is today all people have to do is claim gun and the po po will run out and haul your ass away. trust me on this.

Depends on where you're located. If you're in a more liberal state or in a dense city, I'd probably not recommend it, or if you do, make sure you have all necessary documentation needed to be legal. If you're in my conservative state or rural areas, you probably won't have to worry so much, legality wise. Where you feel like you may need it is up to you. I'd also make sure that you probably disclose it your employer just in case they were to find it without knowing it's there could land you in a rocky position.

Personal experience, I'm from MN and do not have a conceal and carry or anything, nor do I so far feel I need to. I don't operate though, so I do not have a pump. I just work on them. 

Haven't met an operator who has disclosed to me that they have one with them, or at least yet.

I used to work in a area where our shop/yard was located in a rough area , I packed and didn't feel comfortable leaving a weapon in my personal vehicle at our yard , so unless I was going into a petrochemical plant or refinery my pistol would go along for the ride , now most companies nowadays do not allow weapons to be carried , so even if you have proper documentation and the company policy states no firearms , you can be ticketed for illegally possessing a firearm , CC does not override company policy in company vehicles or company property. 

I am pretty sure it is illegal to carry a firearm in a commercial vehicle

negative , it is not illegal

I thought only responsible adults could own firearms.......

In 99% of situations you come across you can handle without getting violent , 25 years ago in the US men had a problem they took it outside and handled business like men , nowadays , there's no more having a scuffle without having someone pulling out a weapon of some sort. I do carry in my vehicle but rarely do I carry a sidearm on my person unless I am in the woods or on the water, I am confident in my ability to protect myself and my family in most situations without a weapon, but I'd rather have a gun and not need it than need one and not have it.
