I have been shooting my new HHW95. Several hundred rounds later I backed the let off screw 1/2 turn and like it so far.
I have the following symptoms, felt before and after my 1/2 turn out.
I am new to two stage triggers so.........
I pull the free play up to the wall.
I slowly apply pressure.
50% of the time if I am pulling controlled enough I will feel what seems like it rolling over a "microscopic" grain of sand or burr and stop.
Now I know she is ready, if I apply any more pressure she will let off.
The other 50% of the time I don't feel it. She just goes.
In other words, its hard to make repeat. So I proceed as if there will be no bump and stop. If it stops after the "itty bitty", "teeny tiny", nick, I know I have the option to take another breath or continue.
Talk to me? Is this the 1st stage that is too light and some times its a single stage and sometimes its a two sage trigger?

I have a HW97 with the same little hitch. Looking forward to any answer you get to see what to do. I also have a Hw95 that doesn't have it so would like to get rid of the hitch if I can. I have learned to shoot around it but it would be nice if I could get both triggers the same

While we wait here I look further.
I found this Tuning the Rekord Trigger (http://www.airguns.net/general_rekord_trigger.php).
I looks as if I need a little more or predictable creep, AKA hitch, or nick, because its unpredictable, or comes and goes, or lets say hard to repeat.?
Would pulling up the play to the wall, and then rolling over the hitch be executing the 1st stage?

Also found this in an old thread from another source/forum.
The author says - "I have found the following method easy and effective if only a little adjustment is needed:"
SAFETY NOTE: never make any adjustments whilst the gun is cocked. The gun must always be uncocked (i.e. fired) before making an adjustment. Most of these adjustments can only be tested with the gun cocked; therefore you will need to have a safe backstop and a tin of pellets.
Don't try to cock or fire the action while removed from the stock. Many break barrels use the stock to guide the cocking linkage in a straight line, and can be damaged if you try to cock them without the action fitted. Even if they can be cocked without damaging them, it is still not a good idea.
FURTHER CAUTION: if you back off the sear engagement adjuster too far it may not be possible to fire the gun. You will then have to break the above rule and tighten it up a little at a time whilst keeping the loaded gun pointed at the safe backstop until you can release the trigger.
Remove trigger guard and replace screws using spacing washers (or modified trigger guard) so action is secure in stock.
Back off the preload screw (the big slotted user-adjustable one) all the way until the first stage is very light, but not floppy. This will allow you to feel the second stage release point and any slight creep more easily.
Back off the sear engagement screw a little, maybe 1/4 to 1/2 turn, this should give a lot of sear engagement.
Test fire the gun and note the second stage weight and possibly creep.
NB: because the preload screw has been backed off so far, the trigger will not automatically move forwards again if the first stage is taken up but the second stage not released. You will have to push it forwards yourself.
Tighten up the sear engagement screw a tiny bit, 1/8 turn or less at a time, to reduce the sear engagement.
Test fire again.
Keep making tiny adjustments to sear engagement until all creep is eliminated but the release is still firm and clean, breaking at perhaps 1-2 pounds pressure, no lighter. Then stop. Do not try to reduce sear engagement until release is very light, you will have overdone it and made the gun unsafe. The Rekord trigger is not designed to be adjusted down to the ounce range.
Now tighten up the preload screw until it has just enough pressure to push the trigger all the way forwards again when the first stage is taken up but then released without firing (gun has to be cocked whilst checking this). Now tighten it up about another half turn, but not much more.
Now you should have a trigger with a light but positive first stage, and an easily felt firm, creep-free second stage.
Do not over-tighten the preload screw hoping that it will make the trigger a bit heavier. It won't, the release is set purely by the second stage sear engagement. If you overdo the preload adjustment you may make the first stage so heavy that you can't properly feel the second stage.
As a final safety test, cock the gun, release the safety catch and whilst holding the gun vertically, well away from you, bang the butt of the gun down on a firm surface a few times as hard as you dare, to make sure the trigger can't be released by accidental knocks. Best not to put a pellet in it (esp. if working indoors ), if it does go off one dry-fire is not realy likely to damage it.
The Rekord trigger is wonderfully simple to adjust, once you understand it. Most other triggers are more difficult because the adjusters al

If I'm not mistaken, you can remove the trigger group from the hw98/98 and the R9 much as you would the hw80/R1. Simply remove the two cross pins and gently remove the reckord trigger group. Once you do this, you can set the trigger, and use the little circle window in the bottom of the casing to view the sear engagement while set in the firing position. You can see where the sear is set and adjust it as needed. This trigger group has very little play so even without the tension (of the spring when compressed and piston latched) it will give you a good idea where your trigger is set. You can also adjust the trigger tension screw. I wouldn't recommend you set the sear "on the edge" but you can get close enough to know how much you may want to go after he trigger group is replaced back in the action. This is also a good opportunity to clean the unit and relubricate the pivot points and contacts of the reckord unit. It's a rather interesging piece of engineering and a good way to familiarize yourself with the reckord trigger group. Good luck. :) tjk

Thanks,
I am hoping not to have to do that kind of surgery. If I'm lucky the adjustment will do it.

The Rekord trigger blade has two rollers on the top of it (inside the group). I'm guessing that you have a microscopic burr on one of your rollers, which is why sometimes you feel it and sometimes you don't. If that's the case, you'll need to take the trigger group apart and do a trigger tune (lots of online help for that) or send it to someone to have it done. Or keep shooting the heck out of it and maybe it will smooth out.
It's been a while since I've dissected a Rekord, but I seem to remember that removing just the trigger blade isn't that difficult. Once you've got it out, inspect the rollers.

Thanks Guys,
Please walk me through what I am supposed to feel as I operate the trigger?
Am I supposed to pull up the free play, apply pressure and feel it roll through a stage to a wall, apply pressure till it lets off?
Maybe I'm slow on the uptake or dyslexic on the two stage trigger so please have patience.
Because sometimes I pull up the free play and the next thing is the let off.
Sometimes it rolls over the little tick and stops until I apply again.
Maybe my tick is too small, or no large enough to hold it?

Mine is set very light. In fact the cocked trigger is floppy until I release the safety. Once the safety is released, the blade firms up and ceases flopping. I lightly take up the very light first stage until I hit the wall, then with a little more pressure, probably well less than a pound, it will break clean with no creep. I adjust the big screw by hand on the fly. I'll often start shooting with it turned in more for a heavier second stage ( still no creep ) and back it out as I become more sensitive and focused during the session. I do bump test the gun every so often because it is set so light, but it has never-slam fired. I have taken the time to clean and relube the trigger, and lightly polish the contact surfaces, and adjust per various how-tos, and it worked out great.
Have fun!
