I started to say you were crazy, but then I thought about feral pigs. Wouldn't pick a 9mm for this but given no other choice, a +P+ solid might be the way to go.
As for issues, a quality ammo manufacturer going over SAAMI spec's would be really, really rare. You could have something like a inset bullet, but again, rare stuff. M&P's and Shields have been known to have the occasional defect leading to a round being unsupported in the chamber or firing out of battery. A +P+ load would probably raise your risk of something bad happening if that were the case. Glock is supposed to have fixed this sort of thing. All in all, wouldn't worry about it. You're more likely to fall and break your leg or get hit by lightning.
And yea.. a .357 for a woods gun. Shot for snakes. Solids for everything else. It's the perfect choice for Texas and New Mexico so maybe as you expand your collection it will be something to consider.
