Yeah, I'm glad to see that you know what you are doing. Sometimes a new gun goes straight to the range without cleaning and oiling. This is not always a problem, but Kahrs have very tight tolerances and stiff springs. They can, and in many cases do need a couple of hundred rounds of fmj run thru them to function reliably. That 1st cleaning and lubrication is really important. I have had 4 new Kahrs and never had the first problem with any of them, all flawless from day one. I have found they like to be very well lubed, and racked the slide a hundred or so times before that 1st range visit. Also important is a firm grip, as any limp wristing will cause the gun not to cycle properly. These are basic things that I think if not done, cause some folks to have problems with their new Kahrs, and other new guns as well.
