My opinion: Best .45 out there for the money, Ruger KP345, about 400 bucks new in most parts of the USA. Reliable, tough, and very doggone accurate. After that other Ruger autos, they're bulky, not pretty, so they've never been popular but they work well. And with a .45 you want a big boned gun. I like Smiths myself as well, 2nd or third generation autos (ex. 645, 4506, etc.), with a five inch barrel you're talking a very powerful weapon. I don't like Glocks for safety reasons. The light trigger on what's essentially a pre-cocked gun is just asking for accidents, in my opinion. I know good shooters (yes plural) who have had accidental discharges with them. They're good combat guns for SWAT teams and the military, not for civilian or regular police use. Plus I would think you're really pushing the frame limits with a .45 load. All just my two cents anyway
