Picked up a .45 acp LC Carbine last week, first one I have owned. Looking forward to the weather getting nicer so I can try it out. A guy ordered it and then decided he didn't really want it so I bought it from him. Plus factor is I had 2 - 13 rnd Glock G21 magazines for sell (I picked them up cheap when I bought a whole bunch of mags from a customer) so I don't have to sell them now. Not sure what optic (probably a red dot) I'm going to put on it. Any thoughts/opinions about the carbine and optics?
