I got my Williams sight yesterday and have been shooting the green laminated gripped one some. The trigger on this isn't as good as the one with walnut grips . Sometime in the next few weeks , I'll be upgrading the third 1377. It has a 12" barrel for now and need some type of front brake with sight . I've got my eye on a air stripper from MikeT , if he can put me a sight on it. Then I'll have to order another Williams sight . kirby
