I recently found this forum and decided that it was time for me to join so as to add some historical facts to the discussion.
In response to usp9 about the broken trigger bar, the original Kahr K9 trigger bar was revised due to factory solicited input to their OEM metal stamping supplier. This step was or is typical due to the supplier’s particular industry expertise. In my prior and 20+ year managing position for that metal stamping OEM supplier of components and assemblies to Kahr, plus other gun companies, I was directly involved with a number of OEM issues.
The originally produced Kahr trigger bars were CNC machined from a block of steel and I designed, and my employer produced, the replacement metal stamped (offset forms with horizontal and vertical tails) trigger bar assembly containing a brazed button and then fully heat treated. Feedback to me was that the replacement was an improvement over the original.
Similar Kahr OEM supplier improvements of my design and my employer’s mfg. we’re of the the double recoil assembly’s tube with formed flange (versus original CNC machined tubes and flanges) and some plastic magazine follower’s metal insert designs and mfg. for the slide stop engagement.
Please note that any OEM supplier suggested improvements were gun company tested and approved before the supplier’s ramping up component or assembly production.
