[RAC]

Hi, every time i see a price of a Luger it comes with a number (%). I think is something about how good is it... and i dont know how to calculate it for my Luger. It has the wood part on the botton of magazine broken, the the hand safty is not working.. but every thing else is fine.. all the numbers match, including the woods parts.. the serial number is 16***, i hope you can help me with te price too, I've seen a few over than U$S1000, but if i tell you how it cost me, you're not gonna believe me.. I'm from argentina, so.. my english is not good... thnx!
