I know nothing, never seen one in real life, but I saw some police trade ins, gone now, and I'm looking now. I guess some have safeties, some don't, at least a couple different sizes, calibers and models. I would want the full size, 45acp, no safety. I don't know about the 2.0 ? Accuracy not too important, reliability is a must. The police guns were 250, sorry I missed that. What's to like? Anything to stay away from? I'm looking to buy a few.
