I’m not sure if anyone will have knowledge to share on this topic but I’ve got to ask. I bought two SW1 Dagger slides to complete home built pistols of the “Glock 19 generation 3” variety. Specifically, the latest FMDA 19.xx. Everything fits and works as it should except the firing pins do not ignite the primers. They strike the primers every single time and do dent them in the center very lightly. It does not seem to matter what ammo I use. I started with cheap wolf and when that didn’t work, I tried Winchester, privi-partisan, and federal because I read the wolf had “hard” primers. It marks the primers with a very slight dent every time. The brand or weight of the ammo makes no difference. I took the barrels out and dry fired them to witness the pin coming through the hole. Is it possible I have out of speck strikers or springs? I’ve cleaned the striker channels and dry fired a bunch. Could the extractor be holding the case head away from the striker far enough to cause light striking? The pistols both seem to be fully in battery. They load, extract, and eject rounds when I manually cycle the slide. Neither pistol has gone bang once after three range trips. I’m kinda bummed out of I’m honest.
I don’t own any other Glock style pistols. That makes it difficult to troubleshoot. If I did, I’d drop the new slides on a known good pistol to check. Does the Dagger work with all generation 3 Glock style frames? I’m thinking it isn’t a frame or trigger issue because they lightly dent every primer on every round that’s cycled thru either pistol when the trigger is pulled. That means the trigger is doing its job right? Is that a bad assumption? Could it be that the striker is not being pulled far enough back? Any suggestions on what to do before sending them back would be greatly appreciated. If you think I’ve done all I can, please tell me. I like to tinker and I enjoy putting my own guns together. I’ve done a lot of reading before trying to assemble my own pistols. I’m just not confident there isn’t something I have missed. Thanks in advance for taking the time to read and respond.
I totally understand why your bummed out and your first line in the second paragraph killed my idea to test. i was gonna say take a firing pin from a known good glock 19, if you had one, and swap it wwith the one in one of the slides.. see if that fixed the issue. I own many daggers , 5 i think, maybe 6, and havent had that issue ever… that said, sometimes a batch of parts can be messed up, and being independent slides, im not sure what they do to test them before they go out if anything. to me it sounds like a firing pin issue, not a spring issue. luckily these things are very cheap and can usually be sourced locally, or even on things like maybe amazon prime for next day delvery if your lucky.. otherwise there are a lot of gun sites out there that can hook you up if you wanna come out of your pocket to test it.. the other side is PSA does have a lifetime warranty. the fact your getting light strikes on every type of ammo you put in makes me think if you go to them for warranty they’ll want you to send in the slides and they’ll test them themselves, however sometimes you may get lucky and tehy may just drop 2 firing pins in the mail to you to see if you can swap them out y ourself to see if that works and fixes the issue. I hate your having this issue but thats basically what i think needs to happen. call up customer service and see what they say they can do to help you.. yes it sucks cause you jsut got them and out of the box they are having issues, but at least they do have a lifetime warranty on all PSA stuff.
Yes to my knowledge the dagger slides work with all gen 3 style glock-inoid style frames. I dont think thats your issue, nor do i think its the trigger, and im really not leaning to the spring, although it could be, but id bet its more of an issue with short out of spec firing pins if i had to bet a lunch on this.
Any chance you got lubricant in the firing pin channel?
A bone head at the range I worked at sprayed CLP on the firing pin tail side of the slides for all our glocks & striker fired handguns. Took about 15 q-tipe to remove the lube along with drying off the firing pin.
It was 100% cause of light primer strikes on 10 of our range rentals.
The lubricant causes hydrostatic lock not letting the firing pin get full force strikes. Glock actually sells the maritime firing pin assembly cups but they have a 1,500 to 2,000 round life.
oh good point. another suggestion is to go ahead and actually clean the entire slide. total disassembly is what i’d recommend.. remove the firing pins, and springs, and all that and clean the firing pin channel and the pin and spring itself.
