I have a P09F and a MCARBO spring kit/polish kit on the way. My trigger is sorta meh, especially the DA trigger, but I shot it well through 150 rounds last Saturday. I'm very pleased with this pistol, but I do want it to have a better trigger. My dilemma is that I think this trigger kit with its reduced powered springs may go a bit too far. Has anyone installed one of these in their pistol?

I have used their kits in both a PO7 and O9. I like the result a great deal. The DA pull is vastly improved and yes the SA pull is lightened…to between 3-3.5 lbs I believe. Their trigger return spring may be the reason and I have thought about calling them to confirm. If so, and you want to maintain the original pull weight on the SA , you can always keep the original spring installed.
I also replaced the trigger shoes with CZ Custom triggers that mimic the geometry of the CZ 75.  This made a big difference to me for shooting pleasure.
They have a great video to follow. If I remember correctly I had a dickens of a time getting the final step completed when setting the decocker back in place. I solved it finally by cocking the hammer for this last step. Good luck and enjoy.

I put the firing pin safety spring in and polished the firing pin safety plunger. I then put the hammer spring in and was satisfied with the trigger pull. Unfortunately I was getting light primer strikes at the range with S&B 124 grain. I reinstalled the original hammer spring and have no issues. I guess I'm going to just stick with the current setup since I like this piece a lot and I shoot it very well.

I pretty much had the same experience, light strikes on ppu and blazer brass. Put the OG main spring back in, have not tested it yet. But DA trigger pull is back up to 9-9.5 lbs, SA stayed 3-3.5 lbs. I have an Mcarbo spring set coming for a p07, i hope it will not light strike.

The more i shoot it and dry fire it with snap caps, the better the DA trigger gets. As of right now, i am very satisfied with the gun and its trigger.
