Do glock 380 jam

Any pistol is capable of jamming. The Glocks are pretty tolerant firearms, but, like any other firearm, they're not invincible.

By the way, if you're in the US, and wanting to buy one, I'll save you the trouble of searching for one and let you know right now you won't find one. They don't fit the criteria for importation under the Gun Control Act of 1968, and are thus unavailable on the US market.
