Trigger

[Gatman12]

I just purchased a new CZ 100 40S&W. I started polishing the trigger bar and interupter and noticed the blueing was worn off the right side of the trigger, top 1/2 inch. All the wear occured working the trigger while polishing with 1500 grit sandpaper. Trigger appears to be dragging during its entire travel. Is this normal? Wondering if this firearm needs to go back to CZ under warranty.

That sounds about normal. I looked at both of my 100's. The 40 S&W has some bluing gone on the upper portion on the right side. I use this pistol mostly right handed and use it a lot more than the 9mm one. I would expect some wear on the right side of the trigger. It doesn't bother me. You could use some cold blue on it. That would at least make it look better.

With the slide off when you pull the trigger does it feel smooth? If it does I would leave well enough alone. If you feel obligated to remove it and polish all touching surfaces, good luck. It is much easier to get the trigger out than to put it back. The 100's have a substantial trigger spring.

Before you decide if you want to send it back to CZ-USA, I would call Mike the gunsmith there, and tell him what is happening.

Good luck.

Thanks for the advice. With the slide off it felt pretty smooth. I polished the right side of the trigger in the wearing area. after polishing I noticed some light scratching on the polished bare metal portion of the trigger and also noticed the bluing in the trigger well on the right side is worn off. Polished the trigger with 1500 grit sand paper, then 800 grit. Went to a dremel tool using semi chrome then buffed it with fine steel wool hoping it would hold cold blue. Well it didnt take the cold blue real well and its still dragging. I'm a little weary of disassembling the trigger to polish the trigger well. The trigger drag can be barely felt if you are checking for it. If I can stop this dragging it will make the trigger that much smoother. I will fire the weapon first then decide. another option is to strip the blueing off the trigger and polish it and have a polished trigger.

If I made putting the trigger back in sound like a bear, I apologize. To me, it seems like the hardest part of re-assembling the pistol. It does not require any special tools, only lots of patience. That is probably why it is the hardest task for me to do. However, if I can do it, anyone can. As an added reason to remove the trigger, you will have full access to most of the internal parts which will benefit from additional polishing, which can make quite a difference. Give it a try.

Pulled the trigger and polished the entire trigger,trigger well and trigger bar. Well worth the effort. Thanks for the encouragement mike.

After you re-assembled the pistol, was there a marked improvement in the smoothness of the trigger pull. The one place I never polished was the area where the trigger might rub up against the frame insert.

Glad it worked out for you.
