Hi,
It looks like a round pin but it's not....just light effect....check out the pic from a different angle...
Overall good conditions, a bit on the rough side, right grip a bit woobly and there are traces of rust....I have checked all markings and stamps...seems all period, but I have also noticed an arsenal proof front of trigger guard....wondering if modifications or repairs have occured with this piece...
Anyway, not for a beauty contest but it is the first Luger and will probably survive me in my start up collection

I will soon be looking for a better shaped model...
Thank you guys for all your support,
Alex
