I'm looking at the S&W 638 and the 642 on-line and I can't tell what's different about them. Bonus question: how do they stack up against the Ruger LCR?
I used to stage my shots--even with an exposed hammer I never used single action. But it was pointed out to me that first, staging offered the same risk as single action in terms of a "light trigger" discharge, and second (and far more important) it was so painfully slow.The 642, though DA only, has a trigger that can be "staged" for more carefully aimed shooting. It took a bit of practice, but I learned to pull the trigger to the break point and hold it while settling on the target, and then squeeze off gently. It's likely not the way you would fire it in a self defense situation, but if you want to hit something small at 10-15 yards, it works quite well.
Well, I was not advocating that for use in a gunfight, although it wouldn't hurt to know that you do have the ability to hit a small target at distances beyond 7 yards. I was only suggesting that with this particular snub-nosed revolver, one doesn't give up too much with the loss of single action capability.For a self defense weapon that a snubbie is, single action and staging seem be be very much in opposition to its purpose.
Actually, the 638 weighs 15.1 oz and the 642 weighs 15 oz.the 638 is quite a bit lighter than the 642 and yes the action as described above is correct. however the lcr is even lighter than the 638 at about 13.5 ozs and would be better compared to the s&w bodyguard 38 at 14.2 ozs. my choice would be s&w bodyguard 38, ruger lcr ( tie for first ) 638 and then the 642 because of the dao
