Recovering these memories is like picking a scab.
When I was young and single, I had a brace of unfired Series 70 1911s and a pair of NIB P-35 Brownings built by a "world-class" gunsmith (now deceased, through no action of mine). Afterwards, none of the four pistols would get through a full magazine without malfunctioning. Since he'd been paid, he took no interest in correcting his work.
On another occasion, years later, I had a special-purpose rifle built by a school's resident gunsmith. The agreement was that it would be ready for use in the class. When I arrived on location I found the work on the rifle had not begun. It was impossible to take the class. I received neither a refund of my deposit nor the return of the parts I supplied. Surprisingly, the school maintained a regal disinterest. Although I could not attend the class already paid for, I received no tuition refund. I was offered a ticket to some future class. Sort of like the "No returns. Store credit only" signs behind the register of low-end retailers.
The result of these experiences was that I transferred my affections to Glocks and AR's. When something breaks that I can't fix on the kitchen table, the gun goes straight back to the mother-ship for repairs. Like the OP, I never again relied on a "gunsmith".
