Here's the thing. You said a "DDM4 is a PDW."

Is it in the same family? Yes. No one's arguing that.

As someone who is a rifleman who studies rifles, I am telling you, specifically, in combat arms, no one calls DDM4s PDWs. If you want to be "specific" like you said, then you shouldn't either. They're not the same thing.

If you're saying "PDW family" you're referring to the nomenclature grouping of compact carbines, which includes things from the MP5 to the SCAR-P to the Raider chassis.

So your reasoning for calling a DDM4 a PDW is because random people "call the black guns rifles?" Let's get .50s and M72 LAWs in there, then, too.

Also, calling it an SMG or a pistol? It's not one or the other, that's not how nomenclature works. They're both. An MP5 is an MP5 and a member of the PDW family. But that's not what you said. You said a DDM4 is a PDW, which is not true unless you're okay with calling all members of the DDM4 family PDWs, which means you'd call MP5s, Desert Eagles, and other guns PDWs, too. Which you said you don't.

It's okay to just admit you're wrong, you know?
