HW/Weihrauch HW97k Questions

The safety works off of the center rod of the piston. At the end of cocking stroke it lifts a level that rides on the safety button and the spring on button is supposed to reset the button. Works exactly the same weather cocking or recocking! So if it's not working there must be something binding or sticking in the safety button itself! Maybe grease or a weak spring?
The only time I've ever seen this problem was to much main piston spring or to much spacing on the spring not letting it get the full stroke! Seems weird to me but maybe they did change something that I'm not aware of.

Not setting the safety is common in HW rifles. All of mine fail to set the safety once in a while. Some guys will tell you that you aren't pulling back far enough on the lever and that may indeed cause some of it. But sometimes they just won't reset even when you are fully back to the stop on your cocking stroke. Even when you cock it again.

When my linkage was worn the safety was intermittent at first. Then failed to set completely. Not long after it would fail to set the trigger unless I really cranked it back hard.

I'm not sure if the slack in the linkage would affect the safety on recocking. I do know I can reset the safety now that the slack in the linkage is repaired.

I'm assuming the bolt tail pushes the safety to the side. It seems like if it worked cocking the gun it would also work re-cocking it. I'm going to dig into mine when I receive my new spring kit. I'll make it a point to figure out how that safety works. I can't imagine why it would set on cocking but not on a re-cock. It must work differently than I visualize.

I saw Steve review a brand new 97 on his review channel, that wouldn't reset the safety.

No telling....

I think it's slack in the linkage causing a short stroke. It's the only thing I can visualize that would cause that. It's just a wild guess. I know the stroke length is super critical. It's really easy to short stroke my 97 now that the new linkage is worn a bit. No doubt a few more thousandths of wear and it will start acting funky. Maybe not reset?

That was the condition that caused me to send mine for warranty. I didn't notice cocking arm slop, but it finally wouldn't lock any more, so I sent it back.

Not necessarily true. Weihrauchs kick the safety out when you finish the cocking stroke against the trigger. The piston can sometimes latch before the safety kicks out if the piston doesn't go the full travel. This can happen for a few reasons. If the the lower guide rim is too thick, the piston skirt can bottoms out on the guide rim before the trigger kicks out the safety. The same can happen if the top hat/ lower guide combination is too long. It can also happen if the cocking stroke is decreased by bent linkages, worn pivots or deformed piston slots. I've seen all of the above.

The amount of piston travel between latching and kicking out the safety is miniscule so problems are rare. When they happen they're usually intermittent at first and sometimes can be muscled away. Usually they become more chronic and eventually the piston won't latch at all. If anyone has an intermittent latching or operating safety the gun has a problem that will likely only get worse.

Be well

You just described my 97's symptoms prior to returning it. You were also kind enough to discuss it with me over the phone at the time. You're a real AGN asset Ron. 👍
