I had a Mk II with the pencil barrel but traded it since I wanted a threaded barrel and it was far cheaper to buy a Buckmark whisper that was already threaded. The threaded alloy uppers and/or integral suppressors for the Ruger are awesome but not cheap.
I'm loving the Browning but I've always got my eye skinned for a good deal on another Ruger. I wouldn't even consider a Smith.
To a much greater extent than most mechanical devices, firearms are terribly unforgiving of any overconfidence, complacency or negligence.
