Tried my extra glock 19 gen 3 oem parts in my dagger …
(1) My dagger is all psa parts except connecter! Originally my trigger pull was 5.0 lbs, When i swapped to glock oem (-) connecter, it went down to 4.5 lbs. When i installed same (-) connecter to a glock oem trigger housing. Trigger pull went up to 5.0 lbs. I was like huh? Tried another glock oem trigger housing. Pull was 5.0 lbs…put back psa trigger housing with glock (-) connecter…went back down to 4.5 lbs…leads me to believe even thou they look alike the angle on the psa trigger housing is slightly different.
(2) Also installed gen 3 trigger bar without the hump. Glock oem trigger bar hole is smaller than psa trigger bar hole, had to open slightly! Once opened! dagger trigger shoe wouldn’t reset all the way forward. Noticed glock oem trigger bar is slightly thicker than the psa trigger bar, and would be a slightly tighter fit in psa trigger shoe. (Nothing a lil polishing wouldn’t fix or different trigger shoe) Not allowing it to move freely forward all the way.
(3) glock 19 oem extractor plunger spring is slightly shorter than psa plunger spring. Outside that all else seemed to work the same with glock oem parts…
Interesting. The general internet assumption is that OEM Glock parts will just drop into PSA Dagger, but your experience argues against that.
(3) Length of the spring is not nec an indicator of the specs. Shorter spring could deliver the same functional performance of that part.
(2) the “hump” or bump is present in later gen Glocks to ensure proper offset of the bar from the side of the frame. Glock engineers must have statistics where the trigger bar failed to depress (missed) the trigger safety plunger device, so they added the bump.
Just to try at one point, I installed all Gen4/5 parts in mine. Gen4 housing with the longer legs snipped off (originally for an 80% project). Everything worked just fine. I do use a Gen5 ejector, but the rest are OEM Dagger parts.
The Dagger parts don’t all work in OEM Glock’s though. Only one I really tried was the striker in a Brownell’s slide, and reading posts it seems common even on actual Glock slides. But the reverse works with OEM Glock strikers working in Daggers.
It could be a thing where they make just enough of a dimensional change so people aren’t buying up all the Dagger parts for OEM guns. Cause they are much cheaper after all. I could easily see people hoarding the parts.
And when I say they worked fine, I mean I shot the gun. Flawless function. Gen 5 G17 extractor and plunger assembly did have noticeably weaker and less consistent ejection, but even dirty it had no malfunctions.
Overall im happy with my dagger! Evening thinking buying the S model.
I was thinking about this topic last night, after a glass of wine or 2, and thought: We may be foolish putting OE Glock parts in the PSA. PSA is PSA, and internal parts built around their platform.
Naïve for us to assume that they were built around the Glock platform, and that Glock parts will work in PSA or PSA parts will work just fine in a Glock. Similar but not the same. I’ve had this experience with CZ and AK parts and clones. Unless standardized (eg “mil spec” in AR’s)- there’s no guarantee that it’s going to work.
You’re welcome to experiment, and do your own R&D, but don’t complain if the parts don’t look the same or function the same.
One companies version of mil spec is different from another, there’s not a single person on here who has an AR-15 who doesn’t have parts from another company! For example I have bought different top quality buffer tubes from different companies and they all fit slightly different on my ar stocks… Some tighter and some looser.
That’s mainly differences in their QC and tolerances. Tolerance stacking IS an issue on an AR but it’s usually never enough to cause issues even when you get bad parts.
Totally agree… But in all my years I have bought several parts from different manufacturers some very high tier names… That the parts were junk either by lack of quality control or manufacturing…
