Left handers are problem solvers by default. I truly feel sorry for right handed people. They lack creativity and critical problem solving skills and never get to experience the joy we feel daily as we over come obstacles put in almost every step of our path. If you think about it, you'd have to watch a lefty for a bit to tell they're left handed but if you drop a right hander in a completely left handed world you'd know in an instant.
All kidding aside, I know I can operate a right handed bolt gun faster and more fluidly left handed than most shooters can right handed. I know that's true as well with 870s and tactical shooting. I never met a right hander who could ejection port load from a side saddle faster than me. I'm sure they're out there but I never met one. The design of an 870 makes it advantageous for a lefty doing ejection port loads from a side saddle.
Okay, sorry for the hijack. Back to our regularly scheduled program.
