My LGS has a like-new MK40 for sale. Reportedly it was a Kahr factory demo with only 2 mags fired. No extra mag (only one 5rd mag), no night sights and it's not an Elite model. They're asking $639. Good deal or ?
I would question why there is only one mag. You didn't say if it has the factory box. I paid $735 for mine new in October. I love the gun it is so smooth and never has had a malfunction of any kind. I would go low on an offer like $550 and see what they say. That's just me. Sometimes cash talks.
