The 642 is a very popular revolver for several reasons...
As you know it is really light, small, and easy to carry. It also is of an adequate enough caliber to change the mind of a two legged attacker. In an "up close and personal" scenario the heavy trigger, minimalist sights, and short sight radius are quite irrelevant.
Now for an in-the-woods encounter... That two legged threat could be up close, however it potentially might be at some distance from multiple threats. Four legged encounters would
preferably be at a distance much greater than arms length. If it comes down to me using a gun, I want to keep that bear, coyote, and rabid critter as far from me as possible. This now makes the 642's really heavy trigger and sight limitations a much more important issue. Also, the increased shooting distances will result in a loss of impact velocity making the somewhat minimalist 38 Special round that much less effective on a dangerous animal.
With that in mind, the 642 would not be my first choice for an in-the-wood carry gun. With it's small size and weight it definitely would be a joy to carry while out hiking. However, it would be a challenge if I needed to make effective hits on a rabid animal scurrying around me at any significant distance. I am not Jerry Miculek and will never pretend to be!
What would I carry? You will hear everyone chime in with their favorites and why. Some are happy with a 22LR and others will settle with nothing less than an 88 Magnum. Realistically, if not in "big bear" country your standard EDC handgun will likely be more than adequate. You will already have a carry system for it and are hopefully at some level of proficiency.
What if your EDC
is a 642, is it still adequate? It definitely would not be my first choice. If all you have is a 642 then carry it. Just have a good understanding of it's capabilities, limitations, and your ability to shoot it.
