Canadian Airgun Forum

At the range today, and the trigger stopped latching, so disobeying long experience of not taking guns apart at the range, I pulled the stock, and found that the "L" shaped trigger spring plate #2740 and #2727 coil spring were in the bottom of the trigger housing. Some diagnosis of trigger operation, as haven't had to look into this gun in a long time, indicated that the cross pin #2721 had slid partially out of the left side of the trigger assembly housing, allowing the "L" plate do disengage. Subsequently, the spacer washer was discovered in the stock.

The pin is a slip fit, non-interference, I applied Blue Loctite into the clearance on both sides, then a cyno glue across each end. Hopefully that solved the problem.

I haven't been able to figure out how to post photos, here, but if anyone is interested I can link to a Dropbox file.

Has anyone else experienced this issue?

I don't have a HW100 so haven't experienced the issue, but on quite a few rifles I have a similar floating pin trigger mechanism. In all cases, the trigger housing or the stock provide what's necessary to prevent the pins from sliding out. It could be yours was not installed fully or something and allowed it to fall out inside the stock. I just can't see HW designing a flaw like that into the trigger. Anyhow, the locktite/super glue is a temporary fix, maybe it will hold long term, but it would be better to find out what's going on and do a proper fix. If you want help posting pics send me a PM and maybe I can fix you up with that.

IDK how to post photos here, perhaps someone can explain?

I would appreciate a conversation regarding this issue, as it may address some aspect which I have overlooked.

As for the stock retaining the pins, the side clearance is far too great to accomplish this. I agree that it is a production oversight which is very strange, being obvious.

*Note: I will go back to my posts to see if I mistakenly stated that the pin fell out. It did not fall out of the trigger group, because there is, as you cautioned, insufficient space for the pin to slide out to the side, before contacting the stock.

Further clarifying, what did happen is that the pin slid out far enough for the side spacer washer (#2741a) to come out of place and fall out, ditto the L shaped lever (#2740).

It is obvious that the pin must be an interference fit into the trigger housing (#2712a), which it is not.

I acquired this used, from a member in Ontario, who is a mechanical trade technician, and our conversations assured me that he is very aware and competent, so IDK the cause, but entertain no idea that something he did is the root cause.

OTOH, the gun was "repaired" by a warranty and repair depot, from which the service was so poor that I will never patronize them again. The problem appeared subsequent to this work, however I understand that correlation is not causation. They may have caused the problem by increasing the size of the hole, installing a worn or undersize pin, however I have no evidence so will not entertain that they are responsible.

Repeating, I know, but I have trouble imagining that any competent manufacturer would fail to take this eventuality into account, so am seeking a more probable cause/solution.

I neglected to measure the pin (#2721) diameter, or the hole, but the fit is so close that my internal measurements will lack sufficient accuracy to be pertinent. Perhaps someone has a pin diameter?

I have included photos and some notes in this Dropbox folder: https://www.dropbox.com/sh/zjcvmrfkdver ... fJZxa?dl=0

Apologies for any confusion on my part, and again that I don't know how to post photos directly.

Photos are a bit tricky, usually they are too big and that's the problem.
I made a short video tutorial. Would you be the Guinea pig and try to follow it and post a photo or two? If it is easy to follow, I'll suggest it as a sticky to help other members who have similar issues.

IDK about the "Guinea" part, but my wife keeps saying that I need to lose weight.

Oops, message says that the video is private.

My bad, it should be viewable now.

Has anyone tried/information on the effects of locating the HW100 trigger spring into the rearward lever hole, and rearward notch?

Indicated by green line.

The video looks to be straight forward. I might give it a try. Thanks!
