His wife might make him throw it away?!?!?!
Eeeeek!
A Luger is a work of art as much as it is a pistol, but as a first gun it may not be what he needs.
They *can* be finicky, until you get the correct mag/ammo combination dialed in, but after that, they are as reliable as any other semi auto.
The frustration level a beginner may experience while getting the combination right may be discouraging to a newbie.
But he may not be planning on shooting much at all, merely keeping one as a fondling piece, to be slavered over and enjoyed.
Yes, it should be bought in person, hopefully with the assistance of someone who knows Lugers.
Even unmatched Lugers can be good shooters, but should still be checked out by someone who has some familiarity with the species.
The toggle action is an amazing bit of engineering, even today, but especially considering it went into production in 1900.
Lugers can bring joy whether you shoot them or not, that is part of their charm.
