I would call Glock and inquire about sending the pistol to them to inspect. I've heard they'll take old Glocks, for example, and make sure they have all the updates they may need. I have heard of some .40 S&W issues with Glock in the past since the pistol was designed as a 9mm, not a .40 S&W or .357 SIG (as opposed to a Glock 20, 29, or 30 which were designed around the 10mm and .45 ACP cartridges. Anyway, it wouldn't hurt to play it safe and see what they have to say.
