MY opinion would be to buy a Ruger P89 for my nightstand/range ... Oh yeah, I already did that.
YOUR opinion should be to buy the gun that makes you smile when you pick it up.
All of the guns are good choices, and you will not regret owning any of them. While all companies occassionally make a lemon, none of those gun companies set out to make a bad or dangerous product. They all want to stay in business and keep making a profit.
Which one did you enjoy shooting the most?
Which was the most comfortable?
Did one trigger rub your finger wrong?
Were you clumsy with the mag release on another?
Did you shoot more accurately with one?
Those are questions that only you can answer.
