I am not the biggest Browning fan in the world but I
highly reccomend the buckmark. It is a very reliable and accurate pistol. I have the Standard that I got for Christmas when I was 16 (now 31). It has had thousands upon thousands of rounds through it and has never jammed up on me, ever.
For your wants I would look at three versions of it. The micro at 2 pounds, the camper at 2 pounds 2 ounces, or the challenge at 1 pound 9 ounces.
