I would never attempt to perform a trigger job. My apologies for poor phrases. What I want to know is twofold: is this a job a smith does to the existing parts for the Kahr or is it more complicated, and second, would it cause other problem? As an example, when the Colt Pony trigger is lightened by altering the spring, the reliability of the pistol can be affected (failure to cycle completely). If anyone knows? Thanks.
