My new arrival, scrubbed bulgarian... shooter or collectible?

[SubgunFun]

I recently picked this up from my wife's uncle. I'm new to the Luger world but I've searched through the old posts here and what I think I have is a scrubbed Bulgarian. However, unlike most I've seen, this one is all matching except for the side plate and barrel (no markings on barrel at all). My only disappointment with shooting it is that it shoots high left (and I know how to shoot... I used to shoot service pistol for the Army Marksmanship Unit and then the All Guard Pistol Team).
Seems like there is a bit of debate on whether these are shooters or collectible. I know I need to get original grips for it and a lanyard loop (anyone out there who can part with these items, let me know). It does have the original extractor (not for sale.. it has matching number to the gun).
Can anyone tell me anything about this or give a better clue on value?
The magazine is not marked anywhere and the follower looks cast (the other magazine in the holster is a very cheap aftermarket). The holster is not marked either (no tool pocket in the holster).
Being family he GAVE this to me for $300!
Thanks in advance for any help...
