Welcome to Glock Talk.

A Gen5 pistol has a radically different Trigger Spring assembly that compresses instead of stretches. It is an integral part of the Trigger Mechanism Housing. An alternative aftermarket Trigger Spring and its installation will be more complicated than the pre-Gen5 stretched coil Trigger Spring, and there are no such devices yet marketed, though no doubt there will soon be such junk available for the gullible to waste their money on.

The pre-Gen5 stretched coil Trigger Spring is THE most common part that breaks (at the hooks) in a Glock pistol. The Gen5 design should almost never break.

I suspect that the new compressed Trigger Spring force is nominally the same 5.0-lbf of the previous-style stretched Trigger Spring. Glock NEVER made coil Trigger Springs with any other rating.

The Gen5 Firing Pin Spring is the same silver-colored 5.5-lbf spring used in pre-Gen5 pistols.

The Gen5 Slide Lock Spring and Slide Stop Springs are now coil springs instead of leaf and wire springs.

The Gen5 Magazine and Magazine Catch Springs are the same as the pre-Gen5 springs.

The ONLY way to alter the trigger pull of Gen5 pistols with OEM parts is to change the connector. Gen5 pistols generally use the DOT connector, although if your G34 is NOT Blue Label, it may have the MINUS connector to give it a trigger pull a little less than 5.0-lbf.

 

Welcome to GT and thanks for the report!!

The G34 Gen5 MOS is on my radar and might be my next purchase. I'm interested in learning more about the pistol and red dots from users such as yourself. Please keep the posts coming!!

 

Thank you for making my want of a G34 Gen 5 so much worse. I promised myself no new guns until I can move to PA.

 

It says what weight connector on the ID sticker on the front of the Glock Case. Will say either 5.5lb or 4.5lb depending on which version you got. '-' Connector is around 20$ if it doesn't have one. Enjoy!

 

What he said.

 

The way you describe your disappointment in the sights leads me to believe that you might really like the red fiber optic front & blackout rear sights from Dawson Precision. I recently installed them on both my Glock 17 & 17L, and they are quite nice!!! Much narrower ‘light bars’ on the left & right of the front sight.

 

Congratulations on your purchase. Can you give more feedback regarding comparison between the 34 and USP please? Thank you.

 

Welcome to GT and congrats on the g34 gen5 .

 

Thanks for all the replies!

I should have said trigger connector in my original post instead of spring.

I'm located in Germany and this is one of the very first gen 5 34s to be sold here. The box label does not say anything about which connector is installed - even gen 5 MOS was hand written on the label at the factory.
I'm going to take the gun apart again today and see if I can see the marking on the connector.

I was slightly disappointed to have my point of impact be so far left from POA, but since the rear sight is centered on the slide, I may give it another range day before adjusting. I tried changing my angle of view on the sights but still hit left. I am 60 years old and wear bifocal glasses which makes iron sights a challenge.

The Dawson sights do look nice and I may end up changing the stock ones out for those. I do prefer all black sights for the range and whatever goes on will have to allow the red dot to still fit. I have a Vortex Venom 3MOA ready to install but I want to get the fixed sights sorted before starting with that.

I will try and and provide more comparison info on the USP Expert. I have a falling plate competition coming up next Friday and was thinking about using the Glock but I stick with the USP at this point until I feel more confident with the Glock.

Thanks again for the replies!

 

I have the Dawson sights on my work gun and really like them. But the front sight is thing (.125”) so you may want to find a thicker one.

As far as shooting left, assuming you are right handed, make sure to keep a good strong hold with your support (left) hand on the gun. I see a lot of officers that I train that have a weak support hand and they often shoot left. That support hand will help mitigate other things going on with your firing hand.

Thank you! I will watch my left hand carefully next time out. I have a lot of cnc machining equipment so I may just whip out a new front sight once I calculate the width needed. I am tending to toward thinking my shooting left to be "operator error" rather than pistol needs sight adjustment...

 

Here are a couple of pics showing the connector bar, I cannot see any markings. Does anyone know which one I have from the pics?

 

The connector is not visible in the photos that you show. You will need to do further disassembly.

Starting with the slide removed as shown in your photos, push out the polymer (trigger housing) pin found at the rear of the grip.

Then lift out the complete trigger housing block including the trigger bar and trigger. You will find the connector press fit into the right side of the block.

Remove the connector and you will see either of the markings are on the back side: a Dot/dimple or a MINUS (horizontal bar) indentation on the connector.

 

I would agree. I used to shoot low left consistently with my Glock. I have the benefit of being able to hand it to another officer to have them shoot it to show me that all my errors are just me. It’s good, but sometimes it’s nice to be able to blame the gun!

If you have the ability, dry fire dry fire dry fire. Get used to that trigger. Also, you can load up a few snap caps or dummy rounds in the magazine. When it clicks when your expecting a bang, you will be able to see that front sight moving and be able to isolate your problem and focus on the trigger pull

 

:welcome:

Thanks for the report.

 

Congrats! That's a good choice for sure.
As soon as i heard they were releasing a Gen 5 G34, I kept an eye out on the shops and shows and bought the first one I came across. I put a Vortex Venom on mine and I love it. My eyes are old and am a fan of the whole red dot movement. Btw, I let my Dad shoot it (he just turned 86) and I didn't think he was going to give it back to me...
From my own experience, the trigger may grow on you. I wasn't huge fan of Glock's until the Gen 5's. Last year I picked up a Gen 5 G26 and the more I shot it, the more I liked it. Since then, my Glock inventory has increased and I now shoot my Glocks more than anything else. Every range trip includes as least two (or more) Glocks (and a j-frame because I apparently like to abuse myself).

 

Wilmsdorfer: by the way congrats on your new G34MOS.5.

My first Glock was also a G34MOS, but a gen 4. I got it last June and have mounted an RMR red dot with Trijicon suppressors steel sights.

I also had issues with the gun shooting left 1.5" at 10 yds. It was in fact the gun, and the problem was solved by drifting the rear sight to the right; as it sits now the rear sight is visiblly offset to the right. (I am RTO at the Sheriff's range, and confirmed the issue with the other trainers.)

Last week I added another Glock, a G19.5, and so far I have been enjoying both Glocks equally!

 

The connector stamps are visible without taking the trigger out of the frame.

That's true when you know what to look for, although not very obvious at first. My old eyes initially had a hellova time id'ing the mark as it's so small.

Interesting. I measured my rear sight yesterday and mine is slightly left in the dovetail so I will drift it over right a bit and work on my finger placement on the trigger. Did a good bit of dry firing yesterday too, not much pulling evident there.

If I was shooting Low and Left I would be sure it was me pulling the shots but mine were all just left, up and down placement was good.

I don't mind having to drift a rear sight a bit to get point of aim and point of impact to agree but no way am I going to be happy if the rear sight has to be drifted way over. If that turns out to be the case, this pistol will be heading back to Glock. Can't have a pistol where I have to aim at the righthand edge of the paper to try and get hits in the 10 ring at 25m. Most all competition over here is done at 25m so the gun has to bring it at that range. My USP Expert sure does - for that matter so does a 30 year old CZ75 my club owns.

I think I'll get things sorted out with the 34. I've been shooting for about 40 years and I generally hit what I aim at... sooner or later.

I did send Glock an email asking which trigger connector is installed in my gun, they should know. I don't want to do anything other than field stripping until I'm sure the the difficulty with sighting in is resolved, just in case the gun does have to go back to Glock

Thanks again everyone for all the tips, will keep you posted!

 

Only had a short amount of time to do some more shooting with the gen 5 34 this week. After doing a bunch of dry firing to get better used to the trigger I found I needed a different trigger finger position that I use for my other single/double action pistols.

I did a bit more shooting from a rest and the POI was only about an inch left of POA. The Range master also fired a mag - he's a lefty and not really a Glock Person - his shots were pretty much OK.

I also measured the position of the rear sight in the dovetail and it is slightly left so I have a sight pusher ordered that should come in Monday.

Will make a slight rear sight adjustment and then I have a Range session coming up Tuesday.

One thing I did find out the hard way: The recoil spring assembly always pops slightly out of place when taking the gun apart. If you don't make sure to press it back FULLY into position before reinstalling the slide assembly, the corner of the RSA digs into the plastic frame and gets stuck. Lesson learned.

 

Finally had a chance at 25 meter precision shooting after I made a slight rear sight adjustment and replaced the front sight with a wider, steel sight I made.

After doing a lot of reading on Glocks shooting left I realized this is a very common problem with shooters new to Glock pistols. I changed my grip to the Enos thumbs parallel to the slide technique which gives very good left hand support. My results were much better. I still had some bad flyers when I failed to watch what I was doing. Still had a lot of 8s, 9s and 10s which for me at 25m is fine.

I do think I will be able to do better as I get more used to the trigger on the Glock. The better sight picture is also a plus, now when the sights are lined up I only have a thin strip of light showing left and right. Makes it easier to keep the front sight centered in the rear sight.

I heard back from Glock and they say all 34s including the gen 5 ship with the 2 Kg trigger connector. It was nice of them to reply to my mail, I know they are busy.

 

Glad you are enjoying it. Funny how different people like different things. I prefer a thinner front sight with lots of light on the sides. I just replaced my Dawson Fiber Optic Sights on my duty gun with the Ameriglo Agents. Although I preferred the thinner Dawson sight, the contrast of the new Ameriglo sight is substantial. Here’s my targets at 5 yards from this morning. The two left circles are from my Springfield XDs and the others are my duty Glock 17.

 

 

not to detract from the OP, but I thought G.5 was limited to 17,19,26.
Now the 34.. did I miss a major news item? Are they making the .40s/sigs/.45/10MM in Gen 5?

 

First they released 17 and 19.

After that... 34 and 26.

No other calibers at this moment.

 

And all of the Gen 5 G34 pistols are MOS.

 

I want the Gen 5 34 bad. I have a 34.4 and it rocks but I don't like the large cutout in the slide. Good write up by the OP.

 

Just an update as I have been doing more shooting with the 34. I mounted a Vortex Venom red dot which is a perfect fit and works very well indeed. I can highly recommend it for this pistol. The supplied mounting plate with the MOS system is ideal. I did shorten some M3 screws to mont the sight but I have a machine shop, so that was a couple of minutes work.

After using a laser bore sighter zeroing the sight was a breeze too. My shooting is continueing to improve, however grip and trigger finger position are critical for tight groups at 25. Meters. I still get frequent flyers - not the airline type - if I loose concentration.

Fit and finish inside and out are absolutely first rate, this is one well made gun. Function has been flawless with gecko, Magtech and S&B plain box 124 grain FMJ ammo.

One note from the video above, the gen 5 34s sold here in the EU do NOT have Ameriglo sights, they have plastic Glock sights.

We’ve seen photos of .40 Gen5s made for a South American police contract, but nothing in the civilian catalog yet.

I’m happy with my 34.4, but if they ever come out with a non-MOS 34.5 I’ll be all over it - I really like the out of the box trigger on my 26.5.

If they released a 22.5 I'd have a pending visit to the LGS :dancingbanana:
