All Gunsmiths are not equal.
I had what I thought to be a relatively easy change out of sights on an S&W MP9. New sight set comprised of a Novak front night sight and 10-8 Performance rear sight to replace the OEM sights. What appeared to be within the individuals competency level was not. One Novak sight rendered useless as a night sight. The plunger spring under the rear sight replaced with a non OEM spring. The rear sight marred.
So this day ventured a road trip to a competent gunsmith whom I have confidence in. The drive is a couple hours one way. Some times you just can’t afford cheap. Quality work cost but in the long run is more cost effective.
As for the other gentleman why demonize him. His was not equal to the task required. He had the correct fixtures, machinery, and tools but simply lacked the knowledge/skill/experience/competency.
