Not always a pistol Edit
Just a note, but someone found Old Faithful being sold with a short Stock, effectively making it a Laser Rifle rather than a Laser Pistol. Does that mean Old Faithful is a cross-class gun, which can be bought either a pistol or a rifle? Video proof, skipped past intro and other irrelevant details.

Every weapon in this game is cross-class, my brudda. Edit
Every gun can be customized and changed to your whim really. Except legendaries. (RIP Unique weapons) - Unless you have mods to change those, too.
