Yes, I've been carrying a Glock 19 using a Victronix tote (
LINK ).
The Bible and Daytimer are both good ideas, but I wanted two things those didn't provide. First, I wanted to carry some additional things such as pepper spray, a small flashlight, a Swiss Army knife, and so forth. And second, I wanted to carry things that would visually misdirect people such that they didn't think I had a weapon.
The tote has 3 compartments. The one closest to my body has the firearm and the pepper spray. The thick area on the outside contains a pen, some cards, a PDA, the flashlight, and the knife. I use that compartment frequently so the various people I interact with are used to seeing the tote, and used to seeing me access harmless items. The outermost compartment has a small first-aid kit.
I've obtained an HK USP 9 SD due to its reputation as a superior firearm. I will ultimately add a match trigger at 4.5 lbs and tritium adjustable sites. The firearm fits in the same area as the Glock.
A further advantage to the tote is the strap. I can carry it over the shoulder or across the chest, which makes it easy for me to have both hands free when necessary.
Now...can I draw rapidly? No. But I lead a quiet life, avoid dangerous areas, and try to maintain some degree of SA, so I hope I won't need to extract the weapon in seconds.
