I guess I don't get the idea of a dedicated "trail gun" - unless you live in grizzly country where four legged creatures "may" be more dangerous than the 2-legged variety. (OR if you need an excuse to purchase a new firearm...
) I train with and carry my main CCW - a Glock 27 - everywhere including on the trail or hunting. It's "relatively lightweight" which is a consideration when camping, hiking or backpacking. I'm much more concerned with 2 legged creatures in my neck of the woods...and .40 S&W is good medicine for them.
I certainly agree a .357 revolver is great -
if that is your main carry, and you are trained up & profiecient on reloading. I would do wonderfully with mine for 5 shots....and then I would have to re-load a revolver in a stressful situation...yikes! I carry mine as a BUG sometimes. ANd I love & appreciate the qualities of a good revolver, I am just
WAY slower reloading than with any semi-auto...I'm sure there are guys on this board who can reload them faster than I can my semi-auto BTW...as I have seen the revolver guys in competitions...awesome!
If I plan on taking small game I bring a shotgun, a .22 rifle or .22 target pistol (ruger MKII or buckmark) in addition to my main defensive, CCW weapon. (However, shotgun or rifle are promoted to primary defensive arms over a pistol if I have either with me
) Personally I am much more proficient in taking small game with a .22LR rifle then a center-fire handgun (at least by group size...)...but who knows. A .22 rifle is minimal in weight and high on utility, but admittedly I don't take one w/ me if I am on a local trail or bike trail out of season...but then I have my trusty, comfortable G27 always.
