I never posted a range report when Santa brought me my Kahr... but I took it out and ran 150 rounds through it right out of the box with shipping grease and everything. No cleaning and relubricating, no racking the slide x00 number of times, etc etc.
Out of the 150 rounds (was gonna go 200, but my hands got tired) I only had ONE failure to feed, and I'm pretty sure I limp-wristed it. It was really cold out (I don't think it broke freezing all day), so the 'shoot five, reload cold rounds, shoot five, reload' routine was doing a number to my delicate geekly hands so I'm pretty sure that the FTF was my own fault.
The spring was noticeably lighter when I was done. And everything was WAY smoother after I cleaned it... between the fouling (100 rounds of my test was with WWB) the crappy packing grease (super sticky stuff), and the cold, I anticipated having some issues, but everything ran smooth.
