I do pretty much what Jammer does.
When I take my carry weapon (walther pps) out of the safe, I drop the mag "yep, 7 rounds in the mag", reinsert the mag, press check "yep, round in the chamber), put the weapon in the holster, take the spare mag out of the safe "yep, 7 rounds", put it in my pocket, lock the safe. Every day, every time.
With the PPS it is not necessary to press check, it has a small hole near the breach that allows you to see the brass cartridge in the chamber. but I usually press check anyway out of habbit. Many of my other guns do not have a loaded chamber indicator.
