Glock ejection?

No Rush · August 11 2014 05:22:32 PM MDT

Hello,
Went to the range today. I shot 2 different types of ammo.
HPR 180gr
Underwood 180gr
The hpr shot fine and ejected fine, but the underwood being more powerful was ejecting differently...
I can't tell if it was going straight up and back or to the right and back?
But it had enough force to cut the top of my forehead?!

What could be the issue? And how do I fix it?

Well which Glock are we talking about G-20? or G-29? Gen 3? Gen 4?
Are you using a factory RSA? Aftermarket RSA?

The slide velocity with the higher impulse ammo can sling the brass into low earth orbit never to be seen again... ${$default_shocked_smiley}$ The slide may be running too fast to the rear and as the casing strikes the ejector, it can pop upward more than to the right. Having stronger RSA spring may help.

Some of the extractors can trap and hold the brass pretty tight, you may see dents on the sides of the brass case as the slide is returning still holding the brass as the slide and barrel come into battery.

Stock Glock 29 gen4

Yes the Gen 4's are having some issues due to the changes made to them, if it is cycling & feeding properly that's a big plus.
There are not many options for tuning the slide velocities on them as of yet! This is because the aftermarket hasn't stepped up much with the newer RSA Glock has produced. I had written Wolff Gun Springs early on about if they were going to make springs and or RSA to be compatible for the gen4 product, at the time they were not.

Underwood ammo is pushing the limits of the cartridge and the RSA being used, has a hard time controlling the slide velocity, therefore the ejection can be extreme. Even Glock is studying these issues, looking at the complaints of failures to feed and pick up rounds left in the magazines. In time aftermarket companies will develop new systems as well.

In the mean time I wish you luck with yours, shooting it more may help it to run better...

I was shopping looking around today on YouTube and other sites.
One channel I saw did a review of several rods and springs for the 20/29's.

I also saw on Glockstore, Wolff, and brass stacker, they all have different styles of assemblies...
Capture, non captured, single spring and dual spring, stainless and tungsten.

My personal thought is to go all out and get a tungsten dual captured with 23lb spring...
But I am new to the 10mm, is this overkill?

What I would do is wait a little while the Gen4 is "NEW" to the marketplace, so not many springs work with the Gen4. Many have tried with varying degrees of success and failures trying what's out there.

Personally I like a non captive system and that's what I run in my gen3 G-20SF Wolff rod with a 22lb spring, I have a 24lb spring but haven't needed it except for heavy testing, and it makes racking the slide tougher as well.

And in the G-29 gen3 I run Wolff two piece non captive rod with 21lb spring set. The 23ld spring set is too much except for testing of very hot ammo, and it makes racking the slide tougher as well.

The Gen4's have a larger purchase in the front of the slide because their rsa is bigger in diameter, and there is a company the makes an adapter, but again people have had varying degrees of success and failure as compared to the stock RSA.

Good luck with your progress... ${$default_wink_smiley}$

Ok so, another question.
When I do wind up changing out the guide rod and spring will that effect me running the .40 and .357 conversion barrels?

The_Shadow · August 14 2014 08:30:13 PM MDT

Have you tried running the 40 and 357Sig conversions with your factory spring? ${$default_huh_smiley}$ They should work and function using the factory RSA. If they don't then you may want to consider a non captive setup, because you will have more options with spring rates. If I were you, I'd contact Wolff Gun Springs and ask questions if they have started work on RSA for your Gen4 Model yet. Since the Gen4's are different from the Gen3 and earlier models, I'd hate to see you waste good money on something that may not suit the pistol's needs. ${$default_roll_eyes_smiley}$

Sorry, I have not had a chance to reply.

I have not bought any conversion barrels yet, but I plan too.
I am wanting to be able to have versatility and be minimal.
I plan on buying a G20 as well.

What in your opinion seems to be the best after market barrels to buy?
I have heard mixed reviews about all of them but I tend to be leaning toward stormlake, I dont know why though...

The_Shadow · August 16 2014 06:36:27 PM MDT

Although I have two Storm Lake barrels a 10mm and 40S&W they are from 2007 as time went on some people actually had issues with later production barrels in the truing cone area inside. The LoneWolf barrels I have are one 357SIG and two 9x25Dillon and all three of them are great chambers and excellent shooters.

If it were me buying 10mm or 40S&W today, I think I would go with a KKM barrel, Lone Wolf Dist. makes a 9" 10mm for the G-20 SF that has me thinking about it... $:-\$ I may opt for a LWD 6" 357Sig to match up with the 9x25Dillon I already have.

But I am a handloader and like to play with various loadings and cartridges... ${$default_cheesy_smiley}$

Do you use the still use the 21lb spring with the conversion barrels?

The_Shadow · August 16 2014 08:07:50 PM MDT

With the G-29 yes the 21 lb spring set works with 10mm, 40S&W, 357Sig and 9x25, although the 10mm cases fly the farthest...with the G-20SF 10mm and 9x25, use the 22 lb spring, both guns are using Wolff Gun Springs non captive rods and springs. My factory Springs work for both but ejection distances are further than with the Wolff setups.
