Range day yesterday and ran two new dagger slides, and both had as many malfunctions as they had good rounds and trying to figure out what the cause may be. Also note that both have new red dot optics on them and I was running 115 grain bulk ammo… I ran P mag as well as Glock factory mags and that didn’t seem to make a difference either. I ran them basically out of the box so I didn’t do any pre-oiling or cleaning because my previous dagger, which was one of the early releases ran just fine that way.
Basically, the man malfunction was the ammo would not seem to go into battery as well as failure to eject. Only had one stove pipe that I can recall, but I had a cycle through a lot of rounds to get into battery which didn’t feel right at all.
If anyone has any recommendations, that would be great!!
Did you pop the slide on and let it rip? Or did you clean and lubricate as recommended? The one thing I have run across in my own daggers with threaded barrels is that they should be cleaned and lubricated well before use. With all that being said, I have had to polish the feed ramp on one of mine with the PSA threaded barrel. It ran flawless after that. I did this solely because the factory finish on the barrel including the feed ramp feels a tad gritty when it dries out thus causing the nose of the round to sometimes not go in to battery. Some other things that cause this are weaker grips. ( Please take no offense to this, just a common thing I have seen from some users)
Make sure you are using the correct length optic screws. Take backplate off, move the extractor plunger. Should move freely and come all the way out. Then look in and see if a screw is visible in the channel coming from the top.
Lube the gun for sure. My OEM Glock’s CAN run dry, but haven’t tried it with the Dagger. But no real reason to run em dry.
Then, play around with the gun before shooting. Rack the slide a bunch. Gets things broken in a bit beforehand.
If the extractor is binding up, it could get to a point where it doesn’t go over the rim of a casing, or gets stuck out it could cause a failure to eject because it’s not holding onto the round properly.
If it’s not any of these things, then I don’t know.
Clear the firearm, take magazine out, pull the trigger, keep trigger depressed, rack slide. Does your slide hang?
I know you aren’t supposed to ride the slide, but does it move into battery after resetting the trigger? Could be linked to common issue with Glocks, which is the firing pin safety.
My Brownell’s slide on a GST-9 wouldn’t go into battery unless I let the trigger reset, but it worked just fine while firing. I don’t think that test really means much when the gun works fine while firing.
If it doesn’t go into battery when you let the slide go completely, I’d call that a problem then.
I just had at least 40% fail to feed malfunctions with the ported barrel/slide combo I just picked up. I don’t think the slide is going back far enough. 115 and 124 factory ammo. Does PSA have a reduced recoil spring? What is the stock spring rate?
Thanks Matt. I don’t have any +P ammo to try. I ordered a 15# spring from Glockstore. Slide is riding up the case, missing the base with both Pmags. Half feeding. 2 smokestacks. It was a disappointing 1st 100 rounds. And a good 6" low at 15 yards.
I have had some people mention shooting low with the 2xl sights. Don’t know why. You may need to swap to a different height front sight. But the cycling issue is more important.
I ground 1/8" off the front sight. Loaded up some 125 FMJ’s I had laying around to about 95% of max went back to the range and got 100% function with 45 rounds/3 mags. Now about 1" low at 15 yards. Feeling better. Just needed more mustard on it.
I fired another 100 rounds of warm’ish handloads and then switched back to blazer factory ammo and today it had no issues with 115 or 124 grain factory ammo. Shooting at about 7 O’clock in the black so I’ll probably file a little more off the front and tap the rear over a tad more.
