I thought some of you snub/J-frame might like to see my Model 40. It's one of the newer ones that can eat +P ammo. It has no lock, but there were a set of keys included which I thought was strange, but whatever! The grip safety is cool, but the trigger pull is like 12Lbs. The trigger is case colored, too. The only thing I did was add a Tyler-T and that's it. I think it's a cool piece! I don't think the Centennials are in production anymore. Please excuse my dark picts from my cheapie camera.
