This article states the goal is 120 days turnaround for all disciplines of forensic testing.

Colorado Springs has their own lab. I cannot find anything to note the turnaround except the examiner says she has a heavy caseload and minimal staff.

This article is from 2010 and averages all 50 states. Says firearms average is 136 days and it may be out of date but I don't think it has gotten significantly faster.

I noticed in looking over several articles that in many cases firearms is the slowest. But I am sure that can't be said for all jurisdictions. Probably is very subjective to the caseload at the time. Also if they have a suspect it is actually slower, meaning they don't have to give it the same priority as they do when they are desperate to get someone off the street.
It leads me to think that once they have their guy locked up they may take well over 90 days to perform ballistics testing. And this back and forth to consider plea negotiations is just a dance to kill time until the ballistics testing can be completed. JMO.
