I think if R* gave the chance to eq rifles/shotguns/lasso or not would been good. I be honest the rifle strap takes away from of the outfits. It'll also be good to of removed weapons to be unarmed etc. Custom Clothing is what I think I'm getting at. Like Red Dead Revolver you could take a rifle or not? Also x2 guns would been nice.
Hope this comes into the a new game if they consider making one. Even getting certian hunting things for outfit scraps been good.
One more thing is it seems you unlock to many good quitaly guns, outfits always right at the end when you can't really re-use them. I think more outfits like Deadly Assassin one should be able to unlock within the first opening missions of games. Takes away all the work you do when you unlock outfits and can't use in storyline or side missions.. just ride around with them one looking for things to do..
