I believe that's not a MK2- its a "standard", also known as a Mk1. Pretty sure what is on the left side is the safety/slide lock, with a heel mag release. If that is the case, mags from later models won't interchange.
Actually as long as they have the rounded mushroom style of the standard, MK I or MK II he’s good. It wasn’t until the 3&4 that they put a flat circle on. Same time they added a bolt release lever like a slide lock.
