Not technically a J frame since it ain't a smith, but it's pretty much a Smith and Wesson M36 which is a J frame, same size anyway. I have an Ultra Lite, very accurate little revolver and the sweetest out of the box trigger I've ever owned. It beats my Smiths, beats my Rugers, only guns I've ever handled that beat it for smooth trigger and controllable in DA is a custom smithed and magnaported M29 Smith and Wesson that a friend has and a Colt Python another friend bought when I was roomin' with him in College. Don't rich college kids miff you off? ;D
Really, though, mine's a fantastic little 17 ounce .38. I liked it so much I had a little custom work done, installed a black dove tailed front sight. I don't know why all fixed sight guns don't have driftable, replaceable sights in various lengths. I had an elevation wire installed for long range work and for shooting super light loads. This little gun is accurate enough to ring a 12" gong consistently at 100 yards. ;D
