Polishing and Trigger Reset

[dbarn]

Wanted to share something I've learned about my SP-01 Tactical after about 7000 rounds.

I've never been happy with the trigger reset using the RP TS from CGW. With this spring the trigger would not move as fast as I could move my finger out to the point of reset. In fact I would get trigger freeze on double taps and strings of rapid fire. Some would say you are out running your trigger, however the problem went away when I went back to the standard factory trigger spring.

The trigger spring has been replaced at least once due to regular maintenance. During this time I would swap in the RP TS and experience the same results. Yesterday a light bulb came on and I decided to look more closely at the sides of my trigger upon removal. On the left side a groove is being worn onto the trigger from a burr just inside the left side of the frame above the trigger slot. Even after 7000 rounds this problem was not going away. I thoroughly polished both my trigger and just inside the left side of the frame using 1000 grit sand paper and a punch that would go inside the trigger slot.

Wow what a difference. I now know how good the CGW RP TS can be. The trigger now follows my finger back out to reset with authority and the benefits of the RP TS can be enjoyed. If you are having the same problem I had, inspect the sides of your trigger upon removal. The marks will tell the tale.

Good discovery.  While I haven't see that myself, some day I might and hopefully I'll remember this thread.

It's always good to share stuff like this.  You know your pistol is not the only one ever made with a problem like that.

I literally just posted about a similar issue with my Tactical Sport. It has a polymer trigger in it now, but I am about to put in one of the flat triggers that Armory Craft stocks.  I will have to pay attention to the solution you described.  I bought the gun used, so I am not sure if it has a reduced power trigger return spring, or it is just worn out.  The issue only seems to happen about 50% of the time, but it drives me insane!

AFAIK, there?s no reduced power trigger spring for the ts/TSO/cm because they use a different type of trigger spring compared to the other CZ75 pistols. I like the polymer better than the aluminum since the overtravel and pretravel screw stays in place and doesn?t wiggle itself out like the aluminum one.

Good find! As you were describing your issue I was getting ahead of myself and thinking about how that is very bizarre and wondered if you had checked those areas out.

Side note, those are worth checking and polishing even if there isn't a bur.
