my 2 cents, having had a gun shop and did formal training, my advice is this, figure out what caliber or calibers you want, and start looking and HOLDING guns you think are potentials, a gun that FITS YOUR hand will be a better buy, than buying any name brand or model that OTHERS tell you to buy!
as guns that fit YOU , you will shoot better period! and like more and be more proficient with it over all!
stuck with name brand guns, and you will be fine, donl;t get caught up in "X" brand ,model, buy what fits you best!
as for bears in PA< the odds of having a conflict with one is extremely rare, as FACT only 1 person in PA's entire history was ever killed by one, just ONE, and that wasn't that long ago, when a traveler threw trash in a dumpster that a mother bear was in, they seen bear climbed a tree that its CUB was in, and well, things went down hill from there for the poor person!
pepper spay might be a better option and less likely to have possible conflicts with a game warden
as YES CC carry is legal now in archery season, but it better be concealed , and that tends to mean HARD to get to, as to having pepper spray out in the open, easier to access! if you follow
and also keep in mind, that when considering BAR caliber hand guns, its NOT Just the caliber to consider, what BULLET you use matters
what works well for HUMANS< doesn;t always work so well on bears!
bears you want solids with deep penetration
for people, you want fast opening and energy transfer
two totally different games being played if you want prime success odds any how!
