The Buck Mark is a splendid pistol. I have the TruGlo front sight on mine- search under my name and 'buck mark' to see one like it. Mine has the round barrel like the Camper model and is a two-tone, silver frame, black upper with laminated black/grey grips.
I can easily hammer out 50 round groups at 50 yards that will rarely stray outside of a 3 inch circle without any strain from offhand. It's like a laser.
I just stuck a Hakko-type sight on it for giggles. I can't wait for it to quit raining so I can get out and play with it.
Sheriff Jim Wilson wrote a review of the lineup awhile back. You can see it from the Gallery of Guns website. I'm sure you're going to get a lot of positive responses from people who own them around here. They're pretty popular, with only a few of us who have had any problems with them- mostly related to extraction and the screws on the top of the receiver, which can be fixed with a little blue Loctite.
Regards,
Rabbit.
