Title: Add loctite to set screw on loaded chamber indicator on late 97B
Post by: Joe L on October 24, 2015, 03:30:39 PM
If you don't, it will loosen and eventually fall out.  Mine had loosened but had maybe 2 turns left before it was gone.  Use a 1.5mm allen wrench, back it out all the way, add a drop of blue loctite, reinstall, snug it down.  Should be there forever.  It isn't a standard set screw either.  It has a small peg on the end to engage the slide hole.  It is a good design, it just needs some thread locker due to the service it is in.

Here is a photo of my 97B"E" bullseye match gun, showing the LCI.  The set screw is on the left, the LCI peg is on the right.

I had the same problem. Put locktite on it and haven't had a problem since.

Do the same on early ones, too. I bought mine in early 1998 and while firing it the mag shot dry. Changed the mag but had a really hard time racking the slide. When I checked the gun I didn't have an LCI. I don't know when it came off the gun, and the gun still worked. I called CZ-USA who sent a new LCI and set screw. As mentioned a drop of blue loctite was added to the screw and no problems since. It's an easy preventative procedure .

Yep learned this a few years ago. One day at the range while shoot my 97BD I notice the lci missing and of all the great luck all the goodies landed on the range table. Loctited it in and has not been an issue since.

Just an FYI:  that loaded chamber indicator also determines the rear of the barrels ultimate lock-up position.  So it's pretty important.  We always Loctite every 97's LCI that comes through the shop, blue Loctite seems to work best.

Were you doing that three years ago when you worked on mine? If so then I won't mess with it...

I found this thread too late. I didn't notice the set screw backing out until I experienced a misfeed.
When I discovered the problem, the loaded chamber indicator pin and spring were nowhere to be found.
Fortunately the plate and retaining screw were still on the gun.
CZ Custom does not have these parts available, and referred me to CZ-USA.
CZ-USA didn't want to send me the parts, they wanted me to send in the gun. Turn around time... 4-6 weeks.
CGW... Sure, we have the parts. Yes, you can install them yourself, it's pretty simple.  Let me get those out to you.
Three days later the parts arrived.  Installed in about 10 minutes. If you know what you're doing, you'll probably do it in 3.
Blue loctite on the set screw.
Great customer service by CGW. If some parts don't show on the web site, give them a call. You might get lucky.
It's a great day.

Thanks OP I have 100 rounds through my BD and I am going out today and get some loctite

Just a followup - I got around to checking my BD and discovered the LCI was in fact loose. It was so loose I am certain the screw would have come out at my next range visit.

I'm REALLY glad I took the time to post this now.  Looks like a common problem to me.

Thanks for this!  I put loctite on my grip screws because those were loose but the thought never crossed my mind to check that indicator screw and it was loose too!

In the original post at the top, I noted it was 1.5mm.  I think that is still correct.

Excellent point on the grip screws too!
This is the way it will go down with my luck: I'll be at the Rainge, minding my own business and the LCI will fly off and into the blouse of the lady shooter on the lane next to me. As I'm trying to explain I'm looking for my LCI she doesn't seem to want to cooperate with the intrusion...yet another Rainge I've been banned from...
Seriously though, I'm thinking of putting a very small peen mark between the edge of the screw and base plate for the LCI, so I know if it ever moves after it gets the blue Locktite treatment.
Just me being anal but with my luck....

Good thread. My LCI fell out on the second mag through the pistol some time back.

You will need a hex wrench, not a screw driver.

I just purchased a new one of these several weeks ago and had to heat the plate to get the set screw to budge. Mine came from the factory solidly Loc-Tited into place. Maybe they have recognized this as a problem. Any how, I finally got it unscrewed, cleaned the old LT off and re-applied and screwed back into place. Thanks Joe for the alert!

OK Question here: I watched a video where at the shot show they mentioned (Angus I think it was) to remove the loaded chamber indicator because it was something that could cause problems if it stuck etc. and now I read something about proper lockup? Should I remove the loaded chamber indicator or not? I did notice that you can't drop a round in the chamber and then drop the slide because of it??

I did't see the shot show video but you must NOT remove the Loaded Chamber Indicator assembly that houses the setscrew as it is needed for lockup location.  You could remove the little silver spring loaded vertical indicator PIN, I suppose, but I've not had any problems with it at all.  I'm not changing mine up.  Works perfectly. 

I don't ever drop a round in the chamber and drop the slide down on it, but yes, the indicator pin would interfere with that, I suppose.  Dropping the slide on a chambered round is also hard on the extractor.   I wouldn't want to do that, loaded chamber indicator pin in place or not, not going to do it. 

I just add some blue loctite on the set screw and left it alone is all I've done.  I've put a lot of rounds through the 97 and never thought about it again.

I was unaware of this problem, so I pulled out my 97BE and checked.  The set screw was tight and my smallest metric Allen key could not budge it.

I guess that CGW took care of this for me when they did the "E" conversion.

Thanks, guys!

Thanks for posting.
New out of the box and completely louse.
Gone locktite it now

You need a  1.5 mm hex key.

Is it a good idee to remove the spring and pin?

I had about 400 rounds through my 97B before I heard something drop onto the shooting bench.  The pin and spring were long gone, but the barrel block and set screw were on the bench.  I have a new pin and spring on the way from CZ right now.

Another thanks for the heads up here. Just bought a new 97 BD yesterday after over two years of searching.

I received this from CZ USA about the LCI

"While rare, it does happen on occasion the set screw that holds the barrel stop plate and loaded chamber indicator on can loosen up under recoil and if not caught can fall out and parts are usually lost. It is perfectly acceptable to take the set screw out, degrease it, and put a drop of red Loctite on the screw to help make sure this does not happen. With any screw in parts such as this they can loosen up over time especially when they take the abuse that the barrel stop does. We recommend keeping an eye on it and check it for tightness form time to time. Let me know if there is anything else you need."

I hope that this helps

I picked up my 97B last year. Set screw wouldn't budge.. So I haven't messed with it. I do keep an eye on it, though.

I picked up my brand new 97b about a month ago and lci set screw was fully seated prior to taking to range but not loc tited. Maybe it's hit and miss on the newer models so be sure to check.

With no thread locker, the set screw WILL loosen.
