...Glock 32... it's indestructible...
A Glock is a very tough pistol, and they will go more rounds than most before things start coming apart. But the Glock and other synthetic frame pistols do have a weakness that is very specific to synthetic frames. They are vulnerable to impact damage to the frames. Honestly this is a very small deal as it's rare a pistol is taken out of action from impact damage, but it does happen on battlefields. Guys running with a pistol in their hands, they take a face plant, and the pistol goes down hard on a rock. I've seen broken dust covers and even grips that were broken half way down (just past the trigger guard).
