Hi All,

First of all thank you for any suggestions or help as its much need as well as appreciated.

I recently took my pf940 build out to the range to run it for the first time and had a issue where the gun is not ejecting the spent shell.

The build went together without many issues. The main problem I had which i believe is related to this issue was once i put the slide on the frame it was very "clunky". It was hard to rack and the slide would bind up.

The slide is a Zaffiri Precision ZPS.2 Complete Upper (OD Green) w/ Zaffiri Precision match grade barrel (fluted). https://80pbuilder.com/zaffiri-precision-zps2-complete-upper-assembly-for-glock-19-g19

This is my first build so I did some initial troubleshooting and polished all of the slide contact points. I removed all of the cerakote in the rail channels as well. This seemed to clear up the clunkyness. I could not longer get the slide to bind up as it was. Occasionally when racking the slide it does not return to full battery and needs a little bump at and it returns fully.

I took it out to test and you can see from the short video below, that no rounds will eject from the gun. If you pull the slide back the round ejects normally and when you drop the slide the gun does return to battery expect for the occasional "bump" to move the slide the last 1/8th or so (not all of the time).

Any help on next steps or trobleshooting areas would be greatly appreciated.

Thank you very much.

Dave!

check that the firing pin safety (& spring), extractor depressor plunger (3 pieces), and extractor are correctly installed. do you have the correct parts, i.e. LCI vs non-LCI, correct depressor plunger bearing, spring, rod, extractor, depending on your flavor. assembly is plastic on plastic, metal on metal.

something wrong with extraction. extractor not gripping cartridge rim, or not maintaining grip on cartridge rim. is it a Gucci extractor, or Glock OEM? I like to start with Glock OEM and make sure it works, before substituting aftermarket parts (one at a time).

or is the extractor gripping the rim, but brass isn't being contacted by ejector, so extractor pulls brass out, brass maintains it's position on breech face, and then is redeposited in chamber? kinda unlikely, due to interaction of cartridge with rounds in mag, etc.

so I'm thinking the extractor isn't getting a grip (wrong parts), or maintaining grip (incorrect assembly) on cartridge in first place.

could be a lot of things.

Having btf ejection problems with mine too. I'm learning not all slides are created equal. Hopefully you have a gen 3 19 and can swap and experiment. Then you can narrow it down to frame part or slide.

I have a p80 complete upper. Btf. I swapped in a gen 5 ejector and apex extractor. It was hit and miss on brass to the face. With 336 ejector in...btf every time and sometimes brass ejecting left of gun...trial and error time...gen 4 ejector otw and more extractors.

 

[rpoL98]

there's a thread on one of the other sites that has some interesting info. Usually the 5th gen ejector solves most issues, regardless FWIW...

"Glock 9mm ejector differences and performance comparison (with video) 336 vs 30274 vs 47021."

Next time to the range, gonna take all three ejectors, and different extractors as well, and play the game of which works best.

Original poster, when you talk about it needing a bump, is the round slightly hung up on the barrel ramp, and the bump chambers the round, rdy to fire? If so, may need to polish that feed ramp.

Post a pic of the bottom of your slide.

Was this ever resolved? Would love to know the solution.

I built 2 PF940's and a Lone Wolf Freedom frame, here was my problems in 2 of them. The slide lock spring was sitting above the frame where you put it into the frame. I ground a little of the spring until it was level with the frame and made sure there was no material inside the hole, this made a big difference. Second was the firing pin safety spring, I replaced with an aftermarket lighter spring.

Were you using a Gen 3 slide lock spring or a Gen 4 slide lock spring. There is a difference and they are not interchangeable. The Freedom Wolf frame is designed to use the Gen 4 slide lock spring. I have seen quite a few people try to use the Gen 3 slide lock spring and they do NOT work in the FW frame.

Or you can use the round Gen 5 slide lock spring too. Which is what I use. The FW frame is designed for either a Gen 4 or Gen 5 slide lock spring.

The Timber Wolf frame is a mix of Gen 3 & 4. LW tells you that the frame will accept either Gen 3 & 4 slides, Gen 3 works great on mine. Gen 4 slide, not so well. It takes a Gen 4 trigger block. The Gen 3 slide lock works just fine if you dig the loose plastic out of the hole and take about a 1/32 of a inch off the bottom. I bought their lower parts kit, that was a mistake. The PF940Cv1 and PF940v2 that I have built haven't had near the problems I had with the Timber Wolf. But in the end I have 3 lowers that work just fine and I learned a lot. The PF940v2 is a 22lr, the PF940Cv1 will be a 9mm, and the Timber Wolf will be a .357 Sig.

 

[CBTENGR]

The Timberwolf might be a mix of Ge3 and Gen 4 but the Freedom Wolf is NOT. The Freedom Wolf is designed to use Gen 4 or Gen parts. The only lower Gen5 parts that will not work is side stop lever.

Every person over on the Marine Gun Builder forum that has tried to use a Gen 3 slide lock spring has ran into problems with it. Again the Freedom Wolf uses the Gen 4 or Gen 5 slide lock spring and trigger pin.

Here is a write I did on building the Freedom Wolf frames.

Freedom Wolf 80% Frame update 6Jul21*

If you look on the LW website, the completion kit is for a Freedom/Timber Wolf. My frame box says Timber, bill says Freedom. I looked up the slide lock spring number on the completion part list, then went to general part list for the Glock/Freedom spring lock and the list says that part fits a gen1-3. I'm not saying your wrong, I'm saying their web site is messed up royal. And the spring in the LW frame is the same spring I installed in the PF940's.

 

[CBTENGR]

And the spring in the LW frame is the same spring I installed in the PF940's.

Myself and others have tried using the Gen 3 slide lock spring in the Freedom Wolf frame and they do not lock in like they should. As you can see from the photo the Gen 4 G19 spring is taller than the Gen 3 G19 spring

And yes there are mistakes on the Lone Wolf website.

Thank you for the information. I will change mine.
