Default J-frame vs. J-magnum frame?

Does anyone have a picture of the old J-frame beside the J-magnum frame? Please post if you do.

Actually, S&W still makes them. The Classic M36, for instance.

I believe the 36 Classic is actually built on the J Mag frame. According to the SCSW, the easy way to tell is the style of cylinder stop lug. Conventional J frames have the cylindrical shaped inserted lug and the J Mag has the integral bar shaped lug.

The stop lug is the projection at the bottom back corner of the frame window in these photos. It limits rearward travel of the cylinder, keeping it from falling off they yoke barrel.

J frame (this one's a Centennial):

If the light-weight J-Mag frame wears-out at the integral cylinder-stop.....throw the frame away. If the older non J-Mag frame wears-out at the cylinder-stop....replace the lug. I suppose if you have a lifetime guarantee....don't matter unless it happens to be one of your cherished frames you'd like to keep, or don't mind the hassle of wondering what you'll get back from Smith in return. I have picked-up a J-Mag frame off the table...opened it up and had the cylinder fall off in my hand. Then...I put it back on the table and walk on.

Not pro or con one way or the other....just sayin'.

Well, not really a defense of the newer integral lug, but I can't imagine how you could possibly "wear one out" with normal use and proper handling. The only purpose it really serves is to prevent the cylinder from sliding off the yoke while fully open. About the only wear I see them getting is from many, many forceful ejections of spent cases. I suppose it could happen, but I can't say that I've ever heard of it being an issue.

But, like you, I do prefer replaceable, serviceable parts.

Is that yoke pivot area different on the J-mag also? Looks in the photos as though there's a ridge to catch the cylinder at the front as well.

I'm not sure if these will help, but I'll throw 'em out there, just in case.

No offense to them that has 'em & likes 'em, but IMHO that "Classic model 36" is a joke. It is NOT a classic model 36, it has the internal lock. And even if you don't mind the lock, the revolver frame was re-shaped to accomodate it which ruined the looks of the gun. Check the curvature of the frame in the area of the hammer. The Bodyguard & Centennial style frame shapes aren't affected by the lock, but the exposed-hammer guns sure are.
It's highly unlikely, but if they came out with a no-lock Classic 36 with the older-style frame shape it'd sure be an improvement.
