Alternative Pistol. G41 maybe?
An alternative pistol to pick up off the map for both sides that maybe can have attachments on it which could make it better than the starting pistols but the base gun itself wouldn't be. Would that pistol be a glock it would have lower damage than both pistols, but could have a semi auto - burst / full auto function that would give it a higher fire rate. You could attach a red dot and if there are ever removable and attachable suppressors added those could go on as well.
