RE: Stalking hogs with a bow
If it makes your friend feel more secure and there is no law against it, then by all means take a pistol. We don't have a season for hogs here in Texas so we there is no firearm in archery season conflict.
Hubby and I have stalked hogs in South Texas while bow hunting and have never had one charge ... one hint that we were in the area and they ran the other way! While hunting with dogs here in East Texas, we have had them charge us, the dogs, the mules, etc.
Good luck and let us know how it works out for you!!
