Stupid question of the week: I can't use a Gen 5 trigger housing in a Gen 3 Glock, right?

I got one just to try the ejector but I assume I can't use the spring-loaded Gen-5 doohickey with Gen 3 trigger bar, connector, etc, right?
 
I would say no, they have different part numbers


trigger housing
gen 3 sp00322
gen 4 sp30275
trigger housing pin
gen 3 sp00427
gen 4 sp07416
 
Aye, but I’ve seen at least one report of a guy installing a gen 4 housing and fixing his gen 3 BTF issue. Maybe I’ll just throw it in and see.
 
I think Gen4/5 ejector trigger housing into Gen3 have been 9mm models.

I am not sure on 40S&W models. I would guess Gen4 ejector trigger housing working in Gen3 models.

Here's 40S&W Gen4 G23 brass to face during break-in of RSA but no BTF after break-in. My experience is similar that I recall occasional BTW with my Gen3 G22/G23 during break in but I am currently not experiencing BTF with either factory ammo or reloads. And with 40-9mm conversion barrels using G17 magazines (Magpul and factory), I do not get BTF and spent cases eject around 4 O'Clock. (Both G22/G23 have stock LCI extractors/SLB and Gen3 ejectors)

That likely wont work, or if it does the gen 4 housing might have a bit of a weebis in a gen 3 frame.

If you are talking about attempting to address a btf issue with gen 4 parts, push the ejectors out of both housings. Take the gen 3 housing and gen 4 ejector, put them together then install.
 
Gen 4 .40 ejector with 9mm extractor works better. Brass goes mostly 5 o’clock or up, some hit my right arm, but none to the face or left. No FTE yet.

might try the Gen 5 9mm ejector just for fun. Won’t shoot .40 with the 9mm ejector ever. Still not sure why....
 
A1EFC795-6078-430E-9C53-4483601775C7.jpeg 9mm ejector is a no go at least in my pistol with .40 mags. It causes the rear of the top cartridge to interfere with feeding and FTF. WHEN it ejected it looked great, about 4 o’clock and consistent. But I guess I can’t have everything. :D

put the .40 ejector back in and shot a couple more mags. Brass straight up or to the right, some hit my shoulder which I’m not fond of, but none to the face or left yet.

I shot a few rounds of double tap +P to satisfy the naysayers and limp wrist accusers, and it all went straight up and about 6 o’clock or 5:30 about three steps behind me.

Gen3 and Gen4 trigger housings are interchangeable. The reason for the different part numbers is because Glock changed the ejector face angle in the Gen4.
OP and I discussed this in PMs.

I am not experiencing BTF with my Gen3 G22/G23 even when using 40-9mm conversion barrels (BCA, KKM, Lone Wolf, Tactical Kinetics) and since they both have LCI extractors, may have updated different angle Gen4 ejectors (AFAIK, Glock started putting in different angle ejectors in Gen3 models to address the BTF issue).

Thanks for the update ... < Taking notes >

Are you using LCI or non-LCI Spring Loaded Bearing with 9mm extractor?

And have you tried Gen4 .40 ejector with .40 extractor?

LCI SLB; OEM .40 extractor was LCI type.

Haven’t tried .40 ejector with .40 extractor yet because I was getting occasional FTE with .40 extractor when shooting 9mm. I guess it’s possible that the new ejector would fix that issue but it seems more logical to me that the .40 extractor doesn’t quite fit within tolerances when shooting 9.

I will say that I’m warming up to the “G17” sized 9mm quite a bit. Easy to shoot well.

I also thought they had to angle the connector a little more to fit the “short frame” but I could be wrong on that and probably am.

I haven't had any issues with Gen3 G22/23/27 properly extracting 9mm brass using conversion barrels.

Give Gen4 ejector a try in your G22/23 with .40 extractor and see how it does with BTF and 9mm brass extraction.
 
G22.3, Brownell’s 40/9 conversion barrel.

FYI gen 3 and gen 4 housings are not IDENTICAL. The bottom of the Gen 3 flares out and the Gen 4 is tapered to a point, I assume to fit into the “short” frame. The holes appear to line up, so I imagine a gen 4 housing would work in a gen 3 but I’m not certain about the reverse.
 
Have you tried a gen 4 9mm ejector # 30274?

With a 40 cal breechface and 9mm case i would strive for close enough, not perfection. The case will have some wiggle room and no amount of extractor tension will reliably hold the case in the optimal position to consistently hot the ejector so it can be flung out in the desired direction.
 
Well I got a G17 mag and tried it with the Gen5 9mm ejector again... it functioned but didn't appear to improve ejection much over the .40 ejector, if any... and the top cartridge was definitely contacting the ejector. The 9mm mag with .40 ejector, .40/9 barrel, and 9mm extractor worked well but I didn't shoot a ton of rounds.

Can someone please check their 9mm Glock, preferably a gen 4 or gen 5, and LMK whether the ejector pushes the rear of the top cartridge down into the mag slightly when you seat the mag? I'm 99% sure this isn't supposed to be happening.
