Firing +P ammunition exclusively for both qualification and duty, an armorer should put hands on the gun every 2000 rounds, as adjustments and parts replacements do become necessary. Firing factory magnums in your 66 armorer inspection was recommended every 1000-1500 rounds and it would be normal to undergo a complete rebuild by 5000 rounds. Dropping back to .38 Special +P+ Q4070 might extend the interval a bit, but inspection every 1500-2000 rounds would still be recommended.
