Sig 320s are rated for +P ammo and can handle it. But +P means “higher pressure” and a steady diet of it will cause faster wear and tear on your gun. +P tends to have more violent recoil and muzzle blast. It should be loaded for carry after practice with FMJ range ammo and not for regular range practice. So shoot a few to see where they hit and how they feel then just save them for carry.
Probably wouldnt hurt to change the recoil spring at a faster rate or use a stiffer spring to begin with like the 40/357 RSA. I know the surplus M17s came with 2 springs one for regular +p nato and one for commercial junk.
More pressure = more wear. There is nothing in your pistol that can’t be replaced economically except the frame and slide itself which are not the primary wear parts beyond break in. Once broken in, the barrel and recoil spring are the main wear parts. I would love to have to replace a barrel because it’s worn out. That means I had fun shooting the gun an incredible number of times.
