Spend a few extra bucks and get a Colt. Remember, with the Colt name, it will keep it's resale value if you ever need to sell or trade it.
And, of course, it's one of the very best as well.
I prefer the LE 6940, but the less expensive LE6920 will also serve you well.
Just my opinion for whatever it's worth, but I'd avoid the Ruger.
I didn't fight to defend your freedom so you could vote to take away mine.
