Ejector angling cartridge?

I have a G19/G23 SCT19 frame that i built a few weeks ago. I noticed when I insert a loaded 9mm magazine the rounds sit as they're supposed to. When i insert a loaded .40 magazine, the cartridge gets pushed down and becomes angled as to not feed parallel to the chamber, see attached pics.


It's been 100% reliable with my PSA Dagger G19 9mm slide and inconsistent with a Patmos G23 .40 slide, the only issue is failure to feed. I'm not sure if it's the ammo (170gr Fiocchi TC FMJ), The magazine (Glock OEM), or possibly the ejector?

The OEM G23 magazine fits VERY tightly into the magazine well when loaded with more than 7rds, requiring me to strip the magazine from the frame. 9mm magazines go in and drop free fine.

Any help with my issue would be much appreciated, thanks.

You probably have an ejector designed for the 9mm, which is angled inward more than the ejector for the 40S&W. If you want to go back and forth, either use the ejector for the 40S&W or buy another trigger housing with ejector and switch them when you switch calibers.

9mm - ejector only is part #336
40S&W - ejector only is part #1882

if you look at the right side of the ejector, you should see the part number stamped on it.

It's an aftermarket ejector trigger housing/assembly, no idea what brand just one in my parts bin. It's the .40 ejector though, i had a 9mm one that was giving me BTF. Is the ejector possibly out of spec?

It’s difficult to say, but I’d try a different housing with ejector designed for the .40. Did you try other mags for the .40 to make sure the mag isn’t over-inserting for some reason?

I have not tried other .40 magazines, I only have the one OEM. I have a relative with a G22 and will be trying some of his magazines sometime this week.

I tried about a dozen or so OEM and aftermarket 9mm mags that were all fine.

Swapping to more OEM parts isn't a bad idea. Glock housings with ejectors are fairly inexpensive anyways. I will order one this week as well and post results.

Do you know anyone with a G23 that could let you try their housing? You could at least check the fit before order the part. My best guess is there is an issue with that housing relative to a stock part.

I don't, but i have a PSA dagger to swap frames/slides on. The mag fits and drops free in that frame loaded and doesn't touch the 9mm ejector. Same FTF issues with that frame though.

Yet another example of all the issues to be expected when attempting to build a copy of a Glock vs. buying an actual Glock and spending time shooting and honing skills vs. constantly fixing issues.

Replace the TMH with another (ideally Glock OEM one) to see what happens. I think the one you have is sitting too low. Otherwise your frame is not within Glock specs.

The 9mm ejector should not be doing that either.

FTF may be separate issue from the ejector pushing on the mags. You won't know until you fix the ejector issue first.

Concur, looks like a 9mm ejector pushing on a .40 cartridge.
Glock ejectors can be pulled out of their respective housings, but you have to buy the TMH (trigger mechanism housing) to get the ejector that you want.

The 9mm ejectors :

I shoot IDPA 100yd iron sight silhouette with a G19 every week or so; building glock clones to me is an experience of learning how to troubleshoot issues with them.
I have had glocks that were out of spec and required diagnosis or factory trips to fix. Considering i only have $200 into this build I'm not upset when issues arise i simply want to know what causes them and how to fix.

I put a digital caliper to both trigger housings in both of my frames, the ejector is indeed sitting lower in my SCT frame compared to my dagger frame. New housing/ ejector to be ordered today.

On a stock setup, both the 40 and 9 tmh will physically fit with either caliber. Some folks don't change it on conversions. So something is physically off on your setup.
