BudsGunShop.com - +P ammo

Betty, you can use +P ammunition, just lube your pistol's slide and frame to slide contact points with a good lube like mil-tec synthetic. This will lessen wear overall by reducing friction. +P+ is not recommended due to manufacturer warranty concerns.

Hi Betty, Yes you can use +P ammunition

Yes it will from Sig "Can I use +P or +P+?
+P Ammo manufactured to SAAMI/CIP/NATO specs is fine to use as a defensive round or for occasional range use. Continual use of this round will make it necessary for more frequent service on the pistol. We do NOT recommend the use of any +P+ round. This may void your warranty."
