For many years now I have been carrying a 1911 3" IWB. I am a leftie, and find that carrying it in a crossdraw fashion has been more comfortable.
I have had my 75B .40 as my nightstand gun for about 5 years, and always considered it to be "too big" to carry IWB. I purchased a Barsony IWB holster to give it a try and discovered it's every bit as comfortable to carry IWB as my 1911.
I've gone ahead and ordered a Savoy Combo LH holster in a crossdraw configuration, that will allow me carry in either IWB or OWB. I'm also using it with the 12-round Mec-Gar magazine without any problems.
How many other people carry their 75B IWB?
