Here’s an update:
Brimstone did a marvelous job on the Mini 30 trigger, reducing trigger pull from around 5 lbs to 3.25 lbs.
I have a Mini 14 for comparison, and the new trigger is smoother. Brimstone was quick, inexpensive, and easy to deal with. They did the trigger work exactly as requested.
Attached is information from Brimstone’s website pointing out that Mini’s have a two stage trigger.
The 3.25 lb pull is measured assuming the shooter makes a single smooth pull through both stages.
It is very nice. After shooting the Brimstone trigger, the unmodified Mini 14 trigger then feels heavy.

If instead of making a single smooth stroke through both trigger stages, the shooter instead slowly pulls the trigger to the end of the first stage, delicate hands can feel the point where only slight additional pressure is needed to complete the trigger pull through the second stage.
At that point, additional vigilance and care is required as it takes very little additional pressure (1.5 lbs) to cause the rifle to fire. It feels a bit like the very light ‘set trigger’ on the CZ527. In the field before hunting with the CZ, I will dry fire 3-5 times using the set trigger to relearn the point where the trigger will fire. I will do the same with the new Mini trigger.
The trigger stop screw is a nice feature, preventing unnecessary rearward movement of the trigger after the rifle fires. They say it gets the shooter to the next shot quicker and with less rifle movement. I like it.
After I do more shooting with the Brimstone trigger, I will do some accuracy testing to compare groupings previously made with the unmodified trigger.
Hoped for accuracy improvement was the reason for the trigger job.
