Hey all...I am interested in purchasing a second USP .45 F w/ night sights as my pistol for my left hand. I am intending on custom fabricating magazine holders that will allow me to reload with both hands simulatenously (is that legal in CA?). I was wondering how I could have a USP w/ the safety lever and the slide lock on the opposite side while maintaining DA/SA? I have no gunsmithing experience, so I would have to have someone else do it for me for a labor charge. Any input on how to could have a left hand friendly USP would be great,,thanks!
