There are reports from early buyers where Kahr was still getting production smoothed out. I won't deny those guns existed. Then again it was one of the things I researched before buying a SIG P938 - early guns under #84k used .380 extractors and were finicky with FTE's constantly reported. I bought mine with the later 9mm extractor and owners are much more pleased with the gun.
Goes to my CW380. It shoots steel cased just fine, but it's underloaded and not a defensive round. So, it doesn't lock back on the last shot. Load up Hornady American Gunner and it works fine. I didn't clean it and haven't yet, it just shoots and shoots. As expected. While early production guns from any maker may have problems, the later ones which report flawless operation are the ones to buy. Unlike the Caracal, or R51, or early SIG's, or Ruger LCP Gen one. My LCP was recalled, then they went thru stages of trying to make the trigger decent (Kahr's reputation is built on good triggers), then they came up with aftermarket enhancements, then they gave up on it and came out with the LCP II. A Rugerized CW380 in size weight and features. In other words the LCP fixed of all it's faults but given a Glock SAFE trigger.
I'll keep carrying my dirty CW380. I trust that more.
As for needing 200 rounds for break in the recommended practice by a lot of pro's is to shoot 500. We have a thread on that and it's interesting reading. Some think a gun should be 100% capable of firing and functioning perfectly with any load they can find on the market. And the professionals still say shoot it and find what load works reliably and stick to it. Your choice, it's your life. If there is anything in dispute, it's whether you live to regret it.
