My sp-01 failed to reset yesterday. After some googling, it seemed that the trigger spring was broken. I was quickly convinced because a piece of trigger spring leg fell out of the gun.
My sp-01 is fairly new. It has only 1000 round through it. But I might have done more than 2000 dry fire. Is this the typical life of a trigger spring?
Thanks.

Mine hasn't failed in over 6000 rounds and probably the same in dry firing. It really depends though

A CGW trigger spring will last over 20k rounds in a 75B, based on my sample of one gun. I put the CGW springs in all three of my CZ's and don't feel there is a need to carry a spare.
Factory springs are reportedly hit or miss. Some last 1k rounds, others 10k.

Joe, the only thing I can find on CGW website is "Reduced power trigger return spring". Is this what you have? Thanks.

When I was working, I was a certified S&W armorer and we preached that all springs should be changed every 5 years/5,000 rounds in duty weapons. In non-duty weapons, I would suggest 5 years/10,000 rounds.

400 plus a few thousand dry fires. I think it was the rapid dry fires that did it. Went with the CGW reduced power as a replacement. Different feel with the reduced power spring and some here don't care for it. I'm ok with it, now.

Yes, and the same spring works in the P-09 also. It will reduce the trigger pull in single action about 5-6 oz over the factory spring but they don't fail, in my experience.

I am going to take my sp-01 to the range this week to see how it will work without a trigger return spring. In case this happened in real life, I would know how to respond. Will let everyone know later.

Mine has lasted 12 years.

I did that when my spring sprung. Worked fine. Just had to push the trigger forward between shots. Really wasn't bad at all. Just a bit slow. A bit of practice might speed things up.

without the trigger spring, the trigger feels better when I do dry firing.

On my 75B, the old style stock TRS broke at somewhere around 20K rds. +/-. I put in the new style spring and have over 40K rds (+ ?? dry fire) on it, and it's still good. Once you buy a spare, they never break. ;)
P.S. The old style TRS was a simple wire wound spring with straight tangs. The newer spring tangs are actually shaped/bent to fit the slots they ride in.

Is the CGW RP-TRS the new style?

I have no idea. It was in the gun when I bought it used in 2004.
