Trigger Stop Setting

[Soligen]

I have a CZ 85 Combat that I am shooting in USPSA Production division. While dry firing this evening I noticed that when the hammer falls, the trigger can still move about 1/4 inch. There is an adjustment screw in the trigger where it looks like I could have the trigger stop sooner. Is this a desireable thing? Is this much travel about right, or considered too much.

I know people will say to try different things until I find what I like, but I'm a newbie and would like opinion before I start messing around with the factory settings.

Thanks

I like a bit more over-travel than most. But, 1/4 inch is likely too much.

Some set their triggers up for zero over-travel (just enough to let the gun function). I think I get a bit more accuracy (I'm not mashing the trigger against the frame on the pull) with some over-travel.

1/4 inch is quite a bit, but is in no way excessive as long as you like it that way.

I like a trigger with minimal overtravel, but will accept whatever overtravel it takes to have 100% reliability.

Personal preference is the guide, just be careful about turning the trigger stop in too far.

There's a fairly recent post in here somewhere offering suggestions for overtravel for 1911 style guns, which basically boiled down to two things - individual preference and reliable gun function (One poster was having a very inconsistent trigger pull weight: light and crisp one round, horribly heavy the next. The suggested explanation was a trigger set to zero overtravel that had grit under the set screw, preventing sufficient travel to release the sear). I wouldn't know the working mechanism of a CZ any more than I would the insides of my computer, but I would guess the same principle applies to your gun as well as a JMB variant.

as much as possible but that is too much! it prevents you from wanking your shots according to travis tomasie and a short trigger will also help.

But after all this things its really shooter prefference and experimentation.

I never had problems but i followed his direction and i dont know if it helped.

Thanks for the input. I tried adjustingj the stop a bit, but can't get a screwdriver in there except at an angle - not enough to break teh screw free. At some point I guess I'll need to get a trigger job, and have a gun-smith adjust it.

I have an 85 Combat. The set screw is locked in with some kind of threadlocking glue. Acetone dropped on it repeatedly will soften it up.

Be careful when adjusting an overtravel screw: if you set it to the point where it just barely lets the hammer fall, it will work OK... and tear up the nose of the sear. The 85C hammer (and 1911's also) have a second hammer hook called the "half cock" or "safety" notch and it is a bit taller than the full cock notch where the hammer is released from on a normal trigger pull.

If you set the overtravel to stop the sear at the point it just releases from the full cock notch, the safety notch will hit the sear nose as the hammer falls. After you adjust the OT screw, pull the trigger and hold it bach and slowly rotate the hammer forward to back with your thimb and makes sure it is completely clear of the sear as both hammer hooks pass by. This requires a bit of overtravel be allowed to the trigger.

Hountyhinter - Thanks for the tip!
