Hi, I've had my WC single stage 4lbs for almost a year, about 800 rounds put through it. Did not get any issue. Cleaned the unit today and did a function test. The trigger will fire on a slow reset. I did not modify or do anything to the trigger unit besides cleaning it. It will slam fully forward or catch the half cock notch. Its a cassette type trigger so forsure it cant be the lower. I tried it on another lower and same thing happens.

If you think Im bump firing it, well if I was, its still unsafe. Releasing slowly on reset should always catch the trigger sear. I dont find this on a mil spec trigger.

I do have another WC ttu in 2 stage 3gun model, it works fine and flawless during a function test, even if I tried really hard to duplicate it, the 2 stage works just fine. The primary sear always catches after the disconnecter releases.

Now my question is this a timing issue related to the geometry of a lightweight single stage trigger? Is this why Geissele triggers are almost all 2 stage? I remember hearing somewhere, if somebody was to make a lightweight single stage, there will be some sacrifices in safety and reliablity.

I already contacted WC but today is Sunday. Im hoping to return this 1 stage trigger and trade for a 2 stage. Kinda dissapointed because I loved the single stage

Sounds like the disconnector might need a little work as I have seen that with other triggers.

I was just going to say disconnector. I have the WC MIL single stage trigger and haven't had an issue, but it has a slightly heavier pull.

I HATE two stage triggers. Before you bail on the WC single stage, take the MIL version for a ride.

I think the only single stage i trust at the moment is a milspec trigger. Lol

I think the MIL/LE version have the same geometry as the 4lbs version. Im not sure though.

No comparison to a TTU MIL.

Speaking of which, have you done that per site rules?

When I needed a new spring for my TTU, WC was very quick to say “send it here, no RMA required”. I don’t think they ever charged me for return shipping or for the spring. I need to call again and make sure that wasn’t a mistake. Turnaround was lightning fast.

I’d definitely suggest calling them.

Why did you need a new spring? I thought these were suppose to last a life time. I only shot 800 rounds thru mine and I believe it needs a new spring already.

Im returning it today and they said theyll be happy to exchange it for a 2stage 3gun. Which I already have in another lower. A better design IMO, the primary sear will always catch after the disconnector releases. As the spring gets weaker overtime, itll still be good to go.

Definitely more than 800 rounds. Like, a lot more. And what I would consider abuse, though unintentional.
