Here is the best video on the Mark 23.I put all my effort into the Chemistry portion of my BS and it has so far paid off quite well.
Now back to kinda on topic, I need someone to talk me off the MK23 ledge. I finally played with one at the IGC a couple weekends back, it actually was not bad in the hand despite being huge.
I kind want one just because in all honesty , but I would think really hard about having the slide milled as I am not a fan of the tiny sights on that gun.
