I'm waiting on my concealed weapons as we speak. :) Should be here in the next week or so. I've carried a gun in my car for years though (Sig 45). In MS your car is considered an extension of your home so it's legal to carry a weapon in it without a permit. I've got a gun under my side of the mattress as well (Browning 9mm). I shoot all regularly and am very comfortable doing so.
I've seen the concealed weapon purses at the gun shows but I think they're super ugly. :P I've decided what I'll do is modify any purses I carry to hold the holster for my gun in one of the side pockets. The holster is an inside waist style so it has a snug metal clamp that holds well agaist a flap of material. I'm going to be carrying a Ruger 380 so I won't need a lot of room in the pocket.
I'll be watching this thread to see if any patterns pop up that I like.
