I haven't been able to find the tritium sight with the cocking shoulder that came on my Super Carry Pro for sale any where but if I were putting night sights on a carry gun that is the only sight I'd consider. Last year I had what my doctor called a pinched nerve in my neck that left my left hand for all practical purposes useless. I couldn't rack the slide on most of my 1911's to save my life except for my Super Carry Pro. I could easily slide the gun down my side, hook the rear sight on the edge of my jeans pocket and push down. I could do it just as fast as my son could cock his 1911 using two hands.
I never thought about this before but what if when TSHTF one of your hands was injured and you needed to rack the slide on your gun to get back into the fight? The Super Carry was designed as a carry gun, someone at Kimber must of thought about that when they designed the gun.
