Don't be this guy at the gun store! (via: @LouisianaFirearms)
A customer mistakenly believed the Glock 45 model was chambered in .45 ACP, when it is actually a 9mm pistol. The employee clarified the distinction between model numbers and calibers, highlighting the customer's failure to specify caliber. The customer left without resolving the issue, demonstrating a common pitfall in firearm purchasing.
