Magazine as Foregrip...Bad Form?

[Onslaught]

It makes shooting a revolver LOTS easier as they were designed for lefties. (Sam Colt and Bill Ruger were both lefties)

Very interesting info... I assume you mean Single Action revolvers?

I'm left handed, and have indeed noticed that SA revolvers are quite Lefty-friendly with that loading trap-door on the right side of the pistol...

Modern DA's aren't so friendly though...
