I am also a lefty that is left eye dominate who was forced to adapt to right handed shooting. I knew from a young age that I wanted to go into law enforcement so I taught myself to shoot right handed. I knew how hard it was to get a left handed baseball glove so I knew how hard it would be to get a left handed duty holster! I trained myself to shoot equally well either hand in rifle or pistol. the only weapon I can't shoot right handed is the shotgun when I am bird hunting. My dominate left eye takes over and I can't line up the shot right handed with both eyes open. Now that I am older and able to afford it I am getting a left handed
custom rifle built and I can't wait. The company stocky stocks ( I think they are sponsors here) make some very affordable stocks in left handed configuration for most popular rifle manufactures.
