Drum 1. Four failures to feed (bolt just slid over the top cartridge)
Drum 2. 6 attempts to get it to fire four rounds, at which time it completely stopped

Here's where I need some advice. I'm pretty much looking for the path of least resistance here. Should I call Kahr, send the drums back and wait for them to either fix them or send me new ones or pay some additional coin to get them tweaked (I see that PK does this).
Sending them back makes them accountable for a bad product but what I get back may be no better. Getting them tuned by PK means a good product but extra cash (anyone know the average cost to fix one of these?).
Thanks for the advice!

By the way, it's not the gun. It runs without a hitch with 20s, 30s and the 39 rd drum.
