They are both very well made guns that should be a pleasure to own. Two questions:
1) Which would YOU rather shoot? Personally I would go for the P-H as more useful - target shooting, deer gun, CW re-enactments. But I am not the end user, you are.
2) If uncertain or torn between which you would rather shoot, which is harder to find & which is the better deal? As a hint, Gun Broker currently lists five Uberti Walkers ranging from $260 to $500. GB currently lists three Parker Hale 2 bands from $850 t0 $1300. As with #1 above, I would lean towards the P-H as harder to find & a better deal than the Walker.
Enjoy whichever you choose. :thumbsup:
