You too? The trigger came in Thurs. finally for the wife's Q4 SF. I let the sear housing fall apart too! That was a BITCH to reassemble. At least for the first and hopefully last time! I didn't read the directions since I'd done my Q5 previously. What's this about having to be in battery?My trigger arrived today. The trigger system came in a nice plastic box like a much smaller version of the pistol boxes. I also bought the updated fire control system.
Installation was completed in under 30 minutes. Much of the time was spent re-installing the spring/lever in the sear assembly (fire control group) which had fallen out in shipping.
Altogether I'm very happy with it. The first stage is shorter, there is no perceptible 'second first stage' to push up the firing pin block, the break is a lot cleaner and the overtravel is much less.
I did nothing to the trigger and sear assembly other than install it. I thought about polishing the transfer bar bearing surfaces but decided to just go with it and see how it does. I don't regret doing it that way. I did notice that the transfer bar has some sort of coating or paint, almost like a teflon coating. I'm wondering if it is indeed a friction reducing coating that would be counterproductive to polish off.
I think it's worth noting that in addition to the installation instructions there was another sheet included that warned about the potential of damaging the pistol during stripping with the new trigger. Apparently the slide has to be held perfectly in battery position while triggering the striker. Failure to do so can cause the striker to trip after the slide passes the battery position and can cause damage. If anyone understands this please elaborate.
Received my trigger today, with the adjusted sear overlap housing. Fantastic! Will need to file down the trigger shoe inertia safety a little, even more so than with the plastic triggers.
In addition to all that's been said already:
- the trigger bar guide (small loose piece in 3rd picture) is now of plastic, not metal, reduces friction a LOT = smoother pull
- no regrets spending $240, the trigger creep is gone, overtravel reduced, it's all I ever wanted
