A different from the rest glock ejection thread

[Pwilliams1]

So I have a gen 3 glock 19. Love the gun. No problems at all under normal use. The only issue I'm running into is that I'm seeing weak ejection when shooting suppressed only.

If it matters I'm using a glock threaded barrel, and an osprey 9. The piston is well greased.

I don't want to get glock involved because I don't think there's anything wrong with the gun since it's flawless unsuppressed. I'm wondering if a new extractor spring,new extractor, or new ejector, or some combination of the above will be the best bet.

What say you?

What load?

 

[Pwilliams1]

147 grain.

It's happened with both American eagle and Winchester ranger.

 

[mopar92]

Try something zipper. Either a +p or a 124 grain load.
147 is subsonic. Personally I'd take the slight loss of sound reduction for increased reliabilty. Or try a lighter recoil spring.

 

[Pwilliams1]

That's an option for sure. I was really hoping changing something out would allow me to continue shooting subsonic. I don't have this problem in my with my other hosts.

Thanks for the input.

The extra weight of the suppressor is reducing slide velocity. The barrel and slide move together during the initial stage of recoil so this is when the suppressor affects the recoil velocity. As mopar92 suggested a softer recoil spring would help the ejection. If there is +P ammo which is subsonic that would help as well as the ammo mopar mentioned.

Glocks are not very reliable when used as a suppressor host. They tend to require weaker recoil springs and heavier loads to cycle reliably. You can make one work but they tend to be ammo picky or " dedicated" to a particular load/ recoil spring/ suppressor set-up.

The osprey is also a very heavy can in terms of newer suppressor designs. The recoil force that is required to actuate the neilsen device, cycle the slide, load, reset the action is anemic if you use a 9mm. It will behave similar to limp wrist induced malfunctions.

The HK usp 9 sd is very reliable as a suppressor host. It may be due to a weaker recoil spring. So as other have suggested, try a weaker recoil spring. This may resolve your issue. But it will result in more felt recoil unsuppressed. SIGs also have this issue, so dont feel that its a bad set up. Its just that you have to tweak it a bit to get it running right.

As a general rule.. Browning type guns with tilting barrels( 1911, glocks, sigs, etc) are finicky suppressor host.They will require a bit of research , experimentation and expense to get them to run properly in the suppressed mode. Except for the HK USP pistols. The Beretta 92 also makes a reliable host and will even operate without a neilsen device.The HK and Beretta will run suppressed out of the box. The Glock 21 is also a good gun to suppress, the bigger bullet/ mass tends to actuate the action and neilsen device more efficiently than its 9mm counterparts.

Thanks so much.

My usp9sd and fnx9 both run great. I was hoping to have the glock up to snuff, but I don't want to swap out recoil springs since I shoot that gun unsuppressed quite a bit and it is my go to hd gun.

I was actually looking into a 226 next, and currently have a thread in the fs/t forum. I need to rethink that now.

regardless of a heavier bullet going slower, it provides more mass to push against the slide. A heavier round usually INCREASES the bolt thrust, and not vice versa- a lighter bullet is not going to make a difference. More powder may do the trick, but it shouldn't be necessary in the first place.

 

[SCARCQB]

Heavy bullets like the 147 grain or 158 grain will run in your glock well. Heavier is better in terms of suppressed function.

I run a G17 with a factory threaded barrel and a Tirant-9. I have noticed a softer recoil impulse with the Federal American eagle ammo. Never had a malfunction, but still noticable. My favorite ammo is Speer Lawman 147gr. The lawman is loaded a little hotter, but is still subsonic.

 

[Pwilliams1]

I've had an eye out for some of that. Haven't tried it yet. I'll throw some in with the next ammo order. Thanks for the tip.
