My wife has been using a CCW pocketbook similar to this (but slightly smaller) for years:


She bought two at the time and the second one is approaching end of life, after lots of daily use.  Unfortunately, we can't find a source for a replacement!  Everything is either way bigger than what she would normally use or makes use of a slash opening rather than a top-open design.  Any favored sources, selections, or similar designs that she could peruse online would be greatly appreciated.

I am in the market myself for a purse to carry. this one seems to be able to be either from the top or side. you had mentioned that many are too big, I bet this one is too big too.

Gun Tote'n Mamas. They make something very similar to the picture. Look for the Raven model.

Well Armed Woman has some similar to what your wife had before.

This looks very similar to what your wife had before:

Gun Tote'n Mamas Raven

I have this one. Very easy to draw from.

I think this is the one you posted a pic of in your OP! The pic looks to be the same.
