Glock 44 + Timney Alpha trigger = Yes, it works.

Or, at least I hope it does.

I picked up a Timney Alpha Competition trigger kit to see what the hype is all about. Just installed it into my Glock 44 (.22 LR). I couldn't seem to find any info online about compatibility, and a rep from Timney told me that they have not tested it in a Glock 44 yet to market it as being compatible.

So far, it has passed a full function check and delivers the promised 3lb trigger pull.

Will follow up at the range soon...

Lucky you

Johnny glocks mentioned he did this for his sons G44. He said there was a reset issue that caused a binary fire that he has to do some modifications to fix.

If I find the video source I’ll re-link it.

Looking forward to hearing how it does.

The Timney Alpha Trigger doesn't play well at all with my Advantage Arms conversion upper. It works fine dry firing, but only has about a 50% success rate during actual fire.

Interesting. What were the nature of the failures?

I really like how the new sear mechanism makes it so that the trigger can still be manipulated after the first dry fire "click". Very good for dry practicing.

Only concern I have so far is that the leg of the trigger torsion spring is pressing up against the plastic locking block of the Glock 44 and already leaving a small impression. I wonder if it will get worse and cause issues. Either way, an aluminum/steel locking block should take care of it.

I'm having light strikes, and extraction problems popped up which doesn't make sense.

The L spring is a concern even with steel. Someone previously posted a photo of the spring cutting a slash in the steel lugs of the barrel. IIRC, he trimmed the spring length to not contact the barrel. But, it will always contact the locking block.

Finally got a chance to take it out to the range and put about 10 mags thru the gun. The trigger worked flawlessly, but the reset is definitely not as strong as I would like. It is a bit weak as many others have complained about.

A stronger trigger spring should solve it though.

I think I figured out the problem with the Timney Alpha not playing nice with the Advantage Arms upper. It had nothing to do with the trigger.

It appeared the upper was firing out of battery. That was causing the failures to extract due to the expanded case that was partially out of the chamber. I looked closer and noticed upon racking or cycling, most of the time there was a 1mm gap between the barrel and slide indicating the upper's springs were out of balance. That was probably contributing to some of the other malfunction modes as well.

So, I could either put in a stronger recoil spring or a weaker striker spring. Or I could also consider putting in a weaker extractor spring. But the recoil spring is permanently captured, so it can't be changed. The extractor spring requires removal of a roll pin out of the aluminum slide, which means it can only be done a few times before you would ruin the slide.

My only real option was to swap out the striker spring for a weaker one, which would then allow the slide to close properly and hold the round in battery. So that's exactly what I did. I swapped out the stock striker spring for a 4 pound striker spring and voila! It appears almost all my malfunction problems have disappeared!

Currently it's running 99% after about 200 rounds. That's a far cry from the original 50% failure rate.
