I like the LaRue MBT-2s very much. One of the best $80 a guy can spend to upgrade, IMO. I never tried Rise, but that sale price on a single-stage is pretty enticing. If I had any need, I'd gamble a little cash on that one myself.
Maybe someone can help me out: I'm not following how a lighter trigger spring can cause misfires. Hammer spring, sure thing. But how can a lighter trigger spring cause misfires???
