Mainspring & mainspring guide missing...that's kind of odd; if you were going to make it 'unfireable' then the firing pin, spring, and guide would be more accessible and reasonable to remove...
But I suppose you could replace them and have an 'operable' pistol...Now, the barrel...yes, it's [fairly] easy to replace...But then it's not matching, but should be 'fireable'...
Hmmmm...Could you shoot it with the holes in the barrel??? that's an interesting question...gas would vent and probably drop bullet velocity/travel down considerably...Possibly even 'squib' [bullet never leaves barrel]...And there would be lots of debris from burning powder, maybe some bullet jacket slivers, vent out the holes...Dangerous to anybody to the side...But revolvers function with openings before the barrel, so it's possible...
Strange way to demil a Luger...
