Well - to be honest???
If it shoots, just shoot it?? I think we all get the urge when we get a shooter - to wonder if it will shoot any better if we replace parts? It usually doesn't, tho'
So - my $0.00002 is shoot the snot out of it and save what you'd have spent for other parts towards a matched Luger.. You see - then you'd have two Lugers...
Now - 'splain that to your wife - and let us know how it goes..??!
Best to you!
