Overtravel Screw in a Carry CZ
« on: December 03, 2023, 09:57:08 AM »
I have wrestled with trying to get the trigger in my carry compact to have as little overtravel as possible in both the DA mode and SA mode. Yes I know about making sure the hammer hooks make no contact with the sear and trigger held back. And yes I’ve watched the disco timing videos over and over again only to mess up several disconnectors to the point of no return. While achieving success in SA mode there is always failure in the DA mode.

Yesterday and out of frustration at the range I swapped in a 97B trigger with no overtravel screw. All of the internals of this pistol have been polished and it has the factory disconnector. I was astounded by the accuracy with a smooth trigger pull and overtravel be bleeped. I’ve been fighting a demon that did not need to be fought. How necessary have you found overtravel to be in a defensive pistol?

I would say definitely not necessary. I think it makes little difference for a carry/defensive pistol. Maybe you could argue for a competition pistol where you are chasing the fastest splits possible, it might be a benefit depending on skill, etc. I had a very similar experience where I was running CGW pro-packages with the CGW trigger and it’s over travel screw in my 3 SP01’s (that I use for carry and comp) but switched them out to CZ custom flat DA/SA triggers (which lack overtravel screws) and noticed no significant difference. My splits actually improved very slightly on average.  But, I think that is more related to the CZC trigger profile being more optimal for how I grip the gun and my hand shape/finger length.

I think a strong argument could be made that for a defensive gun an overtravel screw is just another potential failure point (albeit very unlikely if it is adjusted and appropriate threadlocker is used). So something to consider there as well.

Another factor is that I found for my Al-alloy frame P01 omegas the steel overtravel screw from the CGW triggers would actually wear an ident into the frame after significant dry fire / live fire. This renders the screw useless or at least in need of continual adjustment for it to have any effect.

Agree completely with all of the above. I’d be curious to know also how many have adjusted the screw to the point of rubbing ever so slightly on the sear causing possible light strikes in order to achieve a near zero overtravel. In other words where a 13 pound hammer spring would have worked, you now have to go to a 15 pound to overcome the light strikes.

I would absolutely avoid an over travel screw on a carry pistol. Not worth the possible malfunction.

I guess I'm one of those people who don't notice much about a trigger if it's got a nice "wall" and a crisp break.

My finger and brain just take up the initial movement from rest to the wall with no thought on my mind other than sight alignment on the target. 

Overtravel?  What's that?  Were the sights where I wanted them when the trigger broke?  I do sort of realized it but my mind is already on sight alignment for the next shot and during that the trigger has already returned to the wall.
I just keep wasting time and money on other brands trying to find/make one shoot like my P07 and P09.  What is wrong with me?
