As long as you can safely and consistently draw the gun, and are aware of the "drawbacks," I see no problem with it. You did what you needed to.

One thing I've been wanting to do, but just never seem to get around to it, is getting a left-hand holster to mirror my right-hand holster in the event something like that happens to me. In the meantime, I do occasionally practice drawing my 642 from my front left pocket with my left hand, as well as practicing some left-handed, one-hand manipulations. I'm not as good as a leftie, but I can manage.
