Ah, yes, the same old, same old, Smith-Herrero stats, which so*many seem to see as a *sermon on the mount*. I laugh every time I see someone giving advice based on there opinions.
I would suggest doing some serious research as to WHO these guys ARE, any business connections to makers of *spray*, on Smiths part and what Parks Canada, said to Herrero, when as an American draftdodger, he came to Canada and immediately became to act as a *Grizzly Expert*.
I knew him, the *partner* in his stump ranch at Hills, BC, whom he mentions in his book, the 1st. Ed., at least, was among the *hippies* as we called them on my first BCFS silviculture crew when I was a young man in the BCFS in 1969 and I have and have read his tome.
I have had about 60 encounters with Grizzlies over my decades of wilderness and rural bush work in BC, three were at 10 ft., two unarmed and one with a Ruger MKI, 7mmRM and the others at various ranges. I have NEVER shot one because I have never wanted to and have been *in at the death of about a dozen* .
Do I carry spray, NO, never and while it does work, SOMETIMES, I used it once on fighting Rottweilers, got it in my eyes and, given the winds in BCs mountains, decided that it was-is not for me.
Handguns, are VERY tightly regulated here in BC, among the most densely populated Grizzly regions on Earth and while I DID carry a Ruger Redhawk, .44M, with my handloads for a couple of 5 month long seasons as a *Lookoutman*, I am NOT one to advise people to do this.
Now, a .44, .45*or .4I will kill a bear, BUT, doing this requires a level of REAL expertise that very few actually have. I WOULD do so, again, IF I had the opportunity to practice at least 3 times per week and with the heavy *bear loads* that one would carry and use.
So, IF I WERE a bowhunter and I have had friends who were P&Y World Record Grizzly, etc.holders, I would choose the handgun, but, I prefer one of the purpose-built CRF carbines in .375H&H and 9.3x62 I have and heavy Nosler Pts.
Hope this is some help, what I do prefer when in Grizzly country is to carry a little airhorn and these are pretty good at scaring bears off, but, a .44 is better if the bear gets *personal*.
BTW, several friends of friends here HAVE been mauled and NOW want to pack a pistol and this should be legal as in much of the US.
