I have 4(39Carbine, 39D, 39 Octagon,& 1897 Cowboy) of them here right now and will be picking up another(1954 Ballard) this weekend. I still "need" one with the heavier barrel for silhouette. LOL
Triggers can be worked on by a gunsmith.
The older 39s are predomianate at the Lever Action Silhouette matches. That should say something for them.
It must be chambered awfully tight. I have to be really careful what ammo I use. If I buy something like a brick of Remington Thundebolts, they'll hang up left and right in mine. I now shoot CCI standard velocity, and have no problems with them hanging up.
