So for years, I did just that with a G23 & G27 in IWB rigs. Of course, I owned my own business back then and could dress as I chose, so that made it fairly easy to do.
Louie taught that if your primary stopped for any reason during a gunfight, you didn't diagnose it, you pulled it into retention and drew your second pistol and operated in one handed, hence his choice of a chopped G19 for his left hand pistol. He also preached that you shouldn't try to run the secondary pistol two handed as sooner or later, you'd find your primary thumb wrapped over your off hand. He didn't care that you might get your thumb grooved, rather that it could cause a malfunction.
