Title: I guess I'm getting the 9x25 Dillon barrel after all
Post by: Olgo on January 17 2017 06:10:21 AM MST
I've been on the fence for months whether I'd get the 9x25 barrel or not for my G29. I guess I'm gonna get it because I kept thinking about it. As powerful as a 357mag (out of a G29 IMO) yet easier to shoot than a 10 mil I have to consider that option.

The 357mag is a well known man stopper and well reputed as such and I think the 10mm is in the same boat though if not better.

That's my excuse but really it's a novelty for me to have one meaning more toys for my gun.  :D

I have a 40sw and an extended 10mm barrels for it already.  ::)

The 9x25 has always intrigued me and I got my start with a Bar-Sto conversion barrel for my S&W1006 that I purchased from Mike McNett of Double Tap, since then I have gotten the conversions for my G20 6" and G29 3.78".

The other day a guy on Facebook was selling some 9x25 and 357 Sig Dillon dies at a fair price, I tried to get some people who were interested intouch to buy them...even posted here till they were gone... ::)

Oh well, I can handle $100 for the barrel and more for the ammo. Luckily I made a sale on Reverb so it'll offset the cost some.  :D

Can the G29 barrel length make use the extra powder that is in the 9x25 Dillon case as opposed to just using 357 SIG? The G29 has a 3.77" barrel.

Underwood shows 1700fps for a 125 gr XTP in a 9x25 cartridge from a 6" barrel, and 1475fps for a 125 gr XTP in a 357 SIG cartridge from a 4" barrel. The 9x25 has an operating pressure of ~36K psi and the 357 SIG is 40K psi.

I ran some calculations in Quickloads, and the 9x25 is only 50fps faster than the 357 SIG through a 3.77" barrel.

It does take a bit more powder to make a bullet go 50 fps faster.

This video did some comparison with the G20 and G29 using the 9x25 barrels. The G29 got the avg vel of 1522 fps with Uw 125 GD.

With what I have perused on the internet I decided I want a .357 Sig barrel before the 9x25. Of course, it will be awhile before I get any additional barrels for my G29.  It took decades before I bought a 10mm. :)

I've thought of the 357sig but with the power of 10mm I have the 357sig is a downgrade. I prefer the power of the 9x25. I got a 40sw barrel because I have lots of 40sw and also cheaper to buy for the range.

It's interesting though that the 40sw, 357sig, 10mm and the 9x25 Dillon can all use the same magazine.

I received an email from Lone Wolf yesterday and I was told that they are bringing back the stock length 357 barrel for the G29 but in their Alpha Wolf line and it's a few months away from introduction.  They still have a ported version available for it in the regular line. So if you want a stock length they should be on their way soon.

TNoutdoors9 did a test of Underwood 357 SIG with a 125gr GD from a Glock 32 4" barrel and got ~1510fps. That is ~10fps slower from a 0.2" longer barrel. It doesn't seem worth it to shot the 9x25 in a Glock 29.

If you reload your own 357 SIG, you can make the COAL the same as 10mm/45ACP to better fit in the magazine, and it will allow more powder for higher velocities. I think you can load 357 SIG to perform the same as 9x25 in a G29. See picture below of 357 SIG cartridges loaded to 1.260" COAL.

Well, I finally did it. I ordered the LWD 9x25 Dillon standard length barrel for my G29. Also ordered a box of 50 rnd Uw 125 FMJ and two boxes of 20 rnd Uw 124 XTP.

Now that it's over I can get some sleep.   :))

I'm jealous as hell!

I've always loved 357 SIG's.  So I'm getting a 9x25 barrel for my G29 for SD. (when funds and the wife allows)

How do you guys think it will look if I go with a 4.00" barrel vs 3.78"

Also, Olgo, try shooting a 357 sig down the pipe like peeps do the 40 in the 10, 38 in 357, etc etc.

First a NOTE of SAFETY!  Do not shoot a 357 Sig in the 9x25 Dillon chamber, the cartridge will deform as they headspace on the shoulders of the cartridge.  Proper headspacing is critical to longevity of the brass of each of these bottleneck cartridges!  0.000" to less than 0.002" is needed...

I would opt for the longest barrel for the 9x25 Dillon to wring out the best velocity the cartridge has to offer.  I wish the longer barrels were available when I got my conversions.  I actually bought a 6.02" 9x25 Dillon barrel for a G-20 before I bought the gun.  I recently made inquiry to LWD about the 6.02"  357 Sig barrel and they are in the process to switching all the barrels to the Alpha Wolf, to which they said they will be making them soon.

But I'm seriously I'm going to use it for social purposes. I know it will still out perform a .357 SIG from a G32 and even a G31 by leaps and bounds.

Check out this video  https://youtu.be/H_VXhkQkSz4

The Glock 29 with a 3.8" LoneWolf 9x25 barrel averaged 1520-1530ish with Underwood 125 ammo.  I love the 357 SIG and always have, but it would need a 6" barrel to do that. If even then.

By the way, the guy in the video tests a G20 with 6" and 4.6" 9x25 barrels, then the 3.8" 9x25 from a G29

I'm sold on this idea now. That will probably be my first big mod before sights.

TNoutdoors9 did a test of Underwood 357 SIG with a 125gr GD bullet from a Glock 32 4" barrel and got ~1510fps. That is ~10fps slower from a 0.2" longer barrel. It doesn't seem worth it to shot the 9x25 in a Glock 29.

I thought about getting a 9x25 barrel, but decided against it because there wasn't a real advantage over my 10mm or 357 SIG for the majority of situations I would encounter. The 9x25 might work against Grizzly Bears, but for everything else out there a more common caliber like 10mm and 357 SIG should work just as good. We only have black bears in California.

I am working on a 357 SIG Long Neck cartridge. http://10mm-firearms.com/wildcats/357-sig-long-neck/
That cartridge will allow more powder than a standard 357 SIG cartridge, but less than a 9x25 Dillon. In Quickloads, the Long Neck has velocities between 357 SIG and 9x25 Dillon. Anther benefit is that I can shoot either the long neck or standard 357 SIG through the same barrel.

While I want a 9x25 barrel I need an ammunition I can purchase locally. 10mm, 40 S&W, .357 Sig I can buy from Defender Ammunition, Academy Sports, Gander Mountain, and/or Jim's.  I have been to a lot of gun shops and have not seen 9x25 -- yet.  ;D I'll keep looking.

Only two companies make it that I know of. Underwood and DoubleTap. I have the dies to form 10mm, and from what I read not super difficult, I would rather start with 9x25 brass, that is marked 10mm  :D :)) :-* ;D

Interesting thing is, Underwood said they made their 9x25 form 10mm brass and it will be 10mm on the head stamp.

Now they have 9x25 brass as I found out from the ammo I got (1 box of 50 rnd 9x25 125 FMJ and 2 boxes of 20 rnd 9x25 124 XTP).

Another interesting fact for the G29:

Uw 10mm 180 XTP -  1267 fps 642 fpe
Uw 9x25 124 XTP - 1522 fps 643 fpe

ETA: corrections, the 180 vel is from the Storm Lake barrel, the Glock barrel shows 1231 fps 606 fpe
Title: Re: I guess I'm getting the 9x25 Dillon barrel after all
Post by: Pablo on January 24 2017 07:03:08 PM MST
That is interesting.

You need a longer barrel. I love shooting 9x25 out of my 6.2" Glock 20.  Any kind of targeted object downrange. Just shreds it. Sure my 6.8SPC and .308 and other rifles have more power, something about the 9mm, at that speed and crack out of a hand gun that hardly kicks.

Post by: Olgo on January 24 2017 07:22:42 PM MST
When I was shooting the Uw 10mm 180 it smacks my hand good. Now the 9x25 should be easier to shoot and have the same energy.

I'll soon find out at the range.

Also I found after loading up the 9x25 and holstering, it was a lot lighter.

Uw 9x25 124 XTP - 1522 fps 643 fpe


The 9mm bullet will shoot flatter, but will lose its velocity and energy faster.

The 10mm bullet will retain more of its energy down range.

AT least that is what I think will happen.

Just got back from the range. I got one advice to those who's getting a 9x25 barrel, REPLACE YOUR RECOIL SPRING to 21#!!!

With the stock spring the recoil is brutal and it damaged the spring that I'm getting light strikes because it's not returning to full battery. It could be that the spring was already worn out.

Anyway, I'm carrying with the 40sw barrel and Uw 40sw 155 XTP for now and I got the SS 21# spring (stock is 17#) BMed in order.

Unless they changed the stock spring should be 18 lbs.  I leave my Wolff non captive 21 lbs spring set in mine all the time even with 40 S&W and 357 Sig also for the 9x25 too.

Solid like a brick. If I use a 22 or 24# spring, it's too much spring

I have pondered the 9x25 for some years myself.

I took a quick look this am, I see none offered anywhere. I did see sales on them some months back I guess I should have jumped....

Is this now a defunked cartridge?  I see ammo available...

There are no guns currently offered straight up in 9x25, probably never were. It is a wild cat to be sure.  Popular, on the cusp. Barrels were made and more will be made. LW 9X25 will be back.  RWM Extreme did sell some. I guess some were made for race guns as the initial purpose. And custom made for SW 10XX series.

Back when I got into the 9x25 Dillon, I was intrigued by the cartridge being a necked down 10mm and conversion barrels being available for some guns.  My first 9x25 was from Mike McNett of Double Tap with the purchase of a Bar-Sto Barrel he had them make for the S&W1006.  Then later with the G-29 with a LWD factory length and then a LWD 6.02" for the G-20SF.

Was the 357sig a wildcat cartridge that became popular and now a commercial product?

Wow, did you get what it said ??  :o

357sig was NOT made by necking down 40sw casings.

That's true. That's why we say the 357Sig is LIKE a .40SW necked down

The final 357Sig casing becomes the same length as a 40S&W...  However if you neck up a 357Sig the casing is longer than the 40, that means that the already short 40S&W is too short to make the 357Sig from it...

When the 357Sig first came about in the 90's, I actually formed the range brass cases to 40S&W needing to trim them shorter to length.  ::)
