glock conversions

[pakk]

I want a glock 34, but I can't find one. So instead, I just end up reading about glocks.

It is my understanding that the glock 34 and 35 are the same gun except for one is a 9mm and the other is a .40 It has also come to my attention that the there are conversion for the 35 to shoot 9mm.

This will be my first center fire pistol. 9mm seems to be the choice of round when it comes to sport shooting. It does seem to be one of those things that is preference and one will not know till they are able to shoot it extensively.

My long term goal was to purchase a 34 then 35. Maybe a conversion is a good idea? So here come the questions.

1. Can I convert a 35 to a 34 with all glock parts cost effectively?

2. If converting with all glock parts is not a good idea, what about after market? Good idea? Reliable? Will it simulate a 34 effectively?

If you can't tell, I'm a noob. Thanks for your help.

I'm "almost" positive you can buy a G34 barrel and G17 9mm magazines and would be good to go. I haven't done it myself, but I know several people who have G22's and purchased G17 barrels and mags and haven't had any issues. I know it isn't exactly the same thing, but just more info for you.

Do your research, I seem to recall reading about some others having issues with the extractor.

Hopefully someone here has done it and knows for sure.

Also, just because you hear that 9mm is the "choice of round when it comes to sport shooting" doesn't mean it is true. It is cheaper for sure, however, use the round/caliber that you are most comfortable with.

You'll need a conversion barrel: .40 to 9mm.

In MY OPINION, any type of customization/alteration to any gun will lower the reliability. So I recommend buying the gun meant for the caliber. I have a G35 and bought a Lone Wolf conversion 40-9 and had a lot of failure to eject issues.

I agree with all of the posts so far. I have a G35 and it runs without issue. However, I have seen extraction problems when converting from a .40 to 9mm on other guns. With everything equal, the smaller caliber barrel will fit; however, you still use the same slide for the larger caliber. The problem with that is, the extractor and ejector are designed for the larger round. There are small differences in the thickness of the rim from a .40 to a 9mm and the weight of the empty casing after firing is less. The shape and angles of the ejector are made to clear a .40 casing, not a 9mm.

In the end, I see lots of malfunctions. It's just not the greatest idea. As far as the competition thing goes, yes, lots of people prefer the 9mm. (less recoil and in most cases, it's the smallest caliber allowed for competition) If your buying for comp only then maybe, if not, choose the right caliber for the job. If you want to poke small holes in paper at a comp then go for a 9mm!

Just buy an entire upper in another the other caliber from Glockmeister. No reliability problems that way. About a two to three month wait though. Note that the .45 or 10 mm slides need the corresponding size frame though as well as the G26 / G27 frame sizes that need to match.

1) Yes, but not cost effective. You would need to buy a complete G34 upper, and it will cost almost as much as a G35.

2) Yes, there are a few after market conversion barrels, but without changing the extractor and ejector, they may, or may not, run well.


If you want a G34, then get a G34. The G17 and G22 are the same frame. Only the upper is interchangeable. A G17/G22 will accept a G34/G35/G17L/G24/G31.

Yes, you are a noob.... But everyone has to start somewhere. If you can't find a G34, then get a G17.


"It does seem to be one of those things that is preference and one will not know till they are able to shoot it extensively. "

Yes, I ran over 125,000 rounds thru a G21, before I started shooting G17's. How may rounds to you expect to shoot thru your Glock?

Gen 3 G35 + Lone Wolf 9mm conversion barrel + Glock 9mm mags have been 100% reliable for me.

Only change other than the barrel is a stainless guide rod (with stock weight spring) that I use with both the .40 and 9mm barrels. No extractor change, no FTE's.

This^^^^

Mine runs 100% with just the barrel and magazine swap.

Same recoil spring. (for me)

Another advantage to the Glock 35 besides running .40 and 9 with a conversion barrel, is you can also obtain a .357 SIG barrel and run the same G35 mags.

The 9MM conversion barrel from Lonewolf:

This 9MM barrel can also be used in the GLOCK 22 and GLOCK 31. (extended)

I have heard great things about LWD barrels... Even those who have had issues, they would run +p+ and the problems went away.

My wife runs a KKM 40-9 barrel in her g35, stock ejector. No issues with reliability. I have a 9mm ejector just in case, but so far no issues.

Where are you located? I know a place in NorCal that has both a 34 and a 35 (both gen 3's) in stock right now. If you're in NorCal, PM me and I'll tell you where they are at.

The OEM Route
The G34 and G35 use the same frame, so you could essentially have both complete uppers (slide and barrel) assemblies and be able to switch between the two.

The Conversion Route
If you decide to get a conversion barrel from KKM, LWD, or others to be 100% reliable you should change the ejector. You'll also need 9mm GLOCK magazines.

I have a Wolf 40-9mm conversion barrel for my Glock 27. It's my most accurate gun with the conversion barrel in.

[mtnhrdgr2]

I have a Glock22 and I have both a 9mm and a 40S&W compensated conversion barrel. They both work perfectly. I have seen no discernable reliability difference between the stock barrel and the conversion barrels. I have no reliability concerns.

I also run a recoil buffer. At first I thought it was crap as I had around 40% FTEs. Then I realized that I never lubed up the recoil buffer as instructed. Once I did that, no more FTEs. I've been using these conversion barrels and the recoil buffer for at least 1K rounds now.


The only conversion that, in my experience, has not worked as 100% reliable as the conversion barrels is the 22LR conversion barrel & slide combo. It still works good, but I guestimate that I get around 5% FTF using Remington golden bullet 525 bulk pack. It jumps to around 30% FTF when I use CCIs, so I stick with the Rems.
