last round W/ 22/45

[JMC1]

Hello
I have a new 22/45 with a Volquatsen trigger I just installed. The pistol works great with the one exception of the last round will not fire. The first 9 go off just fine but the 10th never goes off. All I need to do is pull the bolt back just enough to reset the trigger and it goes off every time. I’ve put about 400 rounds through it and it happens every time. Anyone have any thoughts?
Thanks.. Jon

I had a similar problem and just re-adjusted the set screws ever so slightly and the problem went away. That may not be YOUR problem but it worked for me. Have you tried a different magazine?

Ya. I've tried 3 different ones.

An 8th of a turn makes all the difference on their system once you get close. Mine wouldn't reset at all when I first put it in and adjusted it and then a very small adjustment made it work fine.
