Ladies I hang with use P-11s and IWB with High Noon Holsters, sometimes getting a deal on blemish or special. They prefer a bit of forward cant.
This gun is also used in belly bands and in clothes with built in holsters. Old method, I am familiar with from being in a business.
Now the P-11 is the only plastic gun these ladies will do. For a smaller gun, they use Beretta Jetfires and 21As and NAA Mini Revlvers. Again these holsters run from the time proven pocket holsters from makers, to "tailored in" clothes to Belly Bands to the Mini being worn around the neck.
P-11 is a niche gun, they prefer to carry 1911s, BHPs , D frames or K frames.
Just using the methods going back - heck I don't know - ladies were doing this when I was a kid in the 50's
Ladies don't do off person carry, like a purse. Some really don't carry a purse to speak of, and the P-11 fills a niche for when guns have to be locked up and other uses.
One lady is 51, 5'3", business suit or business dress.
She has a Lt wt Commander while wearing that dress.
Same as ladies did in the 50's
Tailors, Seamstresses and Shoe Repair folks that know leather, are one's friends.
