I have a 642-1 and was not even aware that there is a 642-2. What if anything is the difference in the two?

I BELIEVE it may just be the presence (or absence) of the internal lock. I know it's that way with the 442s.

I have a 642-1 ct and there is no lock. I believe thats the difference but others with more knowledge will come along and comment I'm sure, Rick.

Yep, SCSW says the -2 change was the addition of the lock.

But, my M442-2, from 2008, does not have the IL.

Best,

I have a 642-2. Yes it has the lock. Bought it new. Have never engaged the lock nor do I plan to. Put about 1500 rounds thru it in 3 years, no malfunctions of any kind (except the 'thumbpiece' came loose and fell off........my fault.......did not know to periodically check it for tightness)

Years ago there were numerous stories of accidental engagement of the internal lock. While admittedly very rare, the fact that it could happen affected the feelings of confidence in S&W revolvers, making some less certain it would go bang when you pulled the trigger. Just to eliminate the little bit of concern is why I had the internal lock removed in my 640. Since I had the choice with the 642 I specified the model without a lock. I was not aware, until this thread that the two variations are identified by the -1 and -2 and thought possibly the -2 represented some other functional or cosmetic change from the original.
