Glock Model 45 Information Thread

[CoryCop25]

I'm posting this thread to see what others have noticed with their G45.

I have the G45 and the 19X but I'd like this thread to be limited to the G45 or at least be specific to the models.

The main reason I'm posting this is because I was recently issued the G45 and none of my after market magazines work in it. I have ETS 22 and 30 rounders, Magpul 17 and 21 rounders and every magazine that I have used other than the Glock magazines have induced a malfunction. I have used the new Gen5 Glock magazines and older Glock brand magazines and all have worked with no issue. Since the G45, I have had ZERO issues with any of the aftermarket magazines until now. I have used these magazines in all generations of Glocks including a Gen5 17 that I use very often.

When these malfunctions occurred, I was using either American Eagle 147gr or Federal 147 HST.

The malfunctions while using the ETS mags were failure to feed and two times, the rounds did not stack properly and were basically loose in the magazine.
The malfunctions in the Magpul magazines were all failure to lock back.

While I use OEMs for the most part, I did use ETS 22rd and Magpul 17 & 21rd mags in my G45 when I shot it the first couple of weeks.

All brass cased ammo (my Magpul Glock mags aren't reliable with steel) and they worked fine with no issues, but I only used one of each magazine one time only so I would know that they have worked in the past.

Since then and 95% of the time, I train only with OEMs, as I've had bad luck with PMAGs and steel. ETS have been fine but OEMs for the most part for me.

I'm not really concerned about the after market mags as I have more OEM mags than all the after market mags combined. I'm just curious because I have had zero issues until the G45.

And I had zero issues with my G45, albeit limited experience.

Good luck in your search.

I have two G45 - one with Glock OEM NS, and the other with the Ameriglo sights. The former has about 700 rounds thru it, the later about 400.

I have used Glock factory mags and Magpul G17 pmags with both and both have been reliable.

In general, both guns have run exceptionally well. I really like the G45.

I have those loads and gl9 17's and 21's. I'll try to shoot those combinations today in some G45s.

[ST911]

Fired 150 rounds of AE9FP and 121 rounds of P9HST2.
21rd pmag failed to go to slide lock a little less than half the time, did not depend on ammo.
17rd pmag failed to feed HST from slide lock a few times, sending round into the ramp. Occurred when mag was partially loaded.
No ETS mags on hand to try.
OEM 17rd and 24rd, no malfunctions.

Got solid reload reps in today. Thanks!

I bought two 19X's and quickly purchased the first 45 that showed up, retail, not blue label. I've shot it several times and it now has roughly 800 rounds thru it. I also recently ordered 60 for our department based on my experiences and the desire to transition back to the 9mm. I have used several generations of factory magazines without failures. I'm not sure why but I've never bought an after market Glock magazine. I have considered a 9mm AR based carbine or pistol and as it would be a toy, might do it then. I'm not knocking on you but why use the after market mags? After the price of the weapon, accessories, ammo, etc it seems to not be the place to save a few dollars.

Is there a minor design change to the interior geometry of the new models that could be enough to cause a tolerance stacking issue?

The 21 rounders are great for training I obtained over half of these magazines for free so why not?

My last count off OEM Glock 17 rounders was 34 so my issue isn't the lack of OEM magazines or saving money, it's the wanting to know why the aftermarket mags don't work.

I honestly think the Magpul mags can work ok when clean, but when it comes to steel cased ammo, it's a friction issue.

Mine worked fine for several hundred rounds, then I started getting failures, mostly some type of failure to feed while using Wolf / Tula (I have a lot of it).

At first, since the mags had been fine, I attributed it to the G19. However when unloading some GL9 mags I would push the round out to unload, and the following round would take an excessive amount of time to feed into position - usually around .5 seconds but sometimes 2-3 seconds. Obviously if you are slow firing, you may not see it. But during any time of moderate rapid fire, this will cause issues.

I haven't had an issue with G17/19 ETS magazines and I think this is because the polymer is slicker than the Magpul mags.

And at first I sidelined the plastic aftermarket mags for training only, then just loaded them up with brass for a rainy day and put them in an ammo can and broke out more OEMs for training. Aftermarket mags were worth the try when you could get them on sale for $12 and OEMs were $25, however I can get OEMs for $19 and aftermarkets are now $15, it's no longer the case (especially with the issues I have with Magpul mags).

I really liked ETS 22rd mags and they have been great. But with OEM 19 / 24 rd mags, they are becoming less and less novel.
