Perhaps I'm not as gun-aspergic as I thought.
Were I to start a firearms company, I'd deign to make every model's designation communicate some information, or at least be distinctive. Reason? It's kind of obnoxious keeping, for example, REMTEK's Glock page on speed-dial so I can cross-reference the completely uninformative tupperware desginations. At least Smith puts a caliber designation in front of their autopistols, so you know something; their revolvers are a bit nuts. The named weapons in Colt's lineup (Lawman, Python, Police Positive, etc) are a bit easier to remember, and the Russian habit of naming weapons after their designers is a boon to quick memorization.
Or maybe I should just hit the books harder.
