Aaron, yes Sir. Glocks have always been +P rated.

Aaron - C&P from Glock Website: "We recommend using ammunition that is manufactured and meets SAAMI or other industry standards, and while some +P ammunition meets these guidelines, +P+ usually does not. This ammunition may generate a higher pressure than standard ammunition, which could shorten the life of the parts of your firearm. " For you information, there are only four pistol calibers in which SAAMI has approved standards for +P rounds - 9mm, 38 Special, 45 ACP and 38 Auto. If you use "+P" ammo of any other caliber, it is NOT SAAMI APPROVED and can void the warranty of your pistol. One can buy, for example 40 S&W +) .. but it is not SAAMI approved, and therefore would void the warranty of your Glock. So ... if you want to keep your warranty ... don't use any +P other than the four calibers SAAMI has approved.

Yes it can cycle them.
