Occassional Use of +P ammo should be fine, but not necessary. Standard Pressure ammo will work just fine! Being able to put your rounds where it will do the most critical work is what is really paramount!
Remington 124 grn Gold Sabre HP's, CCI 124 grn Gold Dot HP's, Winchester Ranger 127 grn SXT HP's, Federal 124 grn HydraShok HP's or EFMJ, are all good choices. Put a box or two through your gun before carrying any of them to make sure!
