I've got a 3.8" 9x25 Dillon barrel now and I love it. Underwood 124 XTPs I got an average of 1541 from a friend's chrono. Accuracy and fit is great with the LWD barrel. I can rapid fire it a lot easier with the 9x25, and that's still in the 650 ft/lbs neighborhood. I have complete confidence in these XTP's. 16" average penetration through denim. I'd say a few of these might shut down a bad guys pump station.
Told ya. :D
If you wanted a semi-auto .357 magnum, why not just get a Coonan?
Because with his G29 he can shoot 10mm, 40sw, 357sig and 9x25 Dillon with the conversion barrels.

I actually would love one. But rimmed cartridge and round limited. Plus they need to make a 9x25 conversion barrel for the 10mm Coonan. ;D
I put a 357 sig in the barrel and it centers up. I think I can shoot 357 sig from the 9x25 barrel just like 40's from the 10mm barrel.
No you can't. The shoulder on the 357sig is shorter and the case mouth will open up.
I said it would shoot not that it would survive. 9x25 vs 9x23
I get it. May work in a pinch if needed to.
Ok, a 357 SIG is basically a .40 cal necked down to 9mm, You even use the same mags and springs, only a barrel swap is required. how about a Super Sig, with a 10mm necked down to 9mm? Oh wait, that is basically a 9X25 Dillon.
Then of course, there is this:
QuoteWhat finally put an end to the 9×25mm Dillon in competition was component wear, magazine capacity and lowering of the USPSA Major power factor from 175 to 165 (160 for IPSC competition). Barrels and compensators in high-pressure cartridges like .38 Super at Major velocities have a much shorter service life than lower-pressure ones. For maximum-permitted length magazines as used in USPSA/IPSC competition, a .38 Super magazine holds more rounds than a 9×25mm Dillon magazine. With the lowering of the USPSA power factor, safety and effectiveness of .38 Super loads improved to a point that the 9×25mm Dillon was no longer competitive and once worn out, pistols were often retired or rebuilt in .38 Super.
So wear and tear could be a problem with 9X25.
Pressure and heat are what wear out barrels fast. Recoil impulse is what wears out the rest of the gun.
So, yeah, a 9X25 loaded full house is going to wear out faster than a 357 Sig or a 38 Super. But, a 9X25 loaded to 38 super velocities will last just as long, if not a bit longer than a 38 super/357 Sig. Depends on if the barrel of the gun wears out first.
If you are shooting 9x25 enough to wear a gun out, can we be friends?

LOL! The 9x25 conversion barrel for my G29 has a thick barrel so it'll last quite a while.
They are thick, here's the end you don't want to be looking at if you're an intruder at 3am.
I'm moving to a 21# spring anyway for my Nuked 10mm's, so component wear will be brought under control also. But so far I have no frame battering after 80 rounds of Underwood's 124gr XTPs.

I don't think it will work. I am guessing the case will open up to 10mm case diameter before the bullet can move into the bore. Once the case no longer can hold the bullet in line with the barrel, the bullet will just flop around in the chamber, and may eventually get forced into the bore sideways.
Place an empty 40S&W case next to an empty 9x25 Dillon case. If the end of the 40 case does not reach the necked down part of the 9x25 case, I doubt a 357 SIG case, which is slightly longer, will hold the bullet.

357 Long Neck (Kayan). You can use heavy cast bullets.

I wrote an article on 357 SIG, and in my research I found its based off the 10mm.The 357 SIG has 23mm brass, the 40 uses 22mm.
Edit:I see you mentioned that too, I missed it the first time around.
My dumb ass has already fired a 357Sig in it, and my son was supposed to keep his eyes on the brass, but lost it. I haven't found it yet, my 29 has never behaved as well as my Ruger P93DC , it's mischievous and throws brass every which way, my Ruger will pile them up neatly, about 10 feet over, at a 45 degree angle from me.
I usually recover 4 to 5 out of 11 fired.

From what I can see in the picture, it looks like the 357 SIG brass will still hold the bullet in line with the bore if it is fired in a 9x25 Dillon barrel.
Did the bullet come close to what you were aiming at?
.
It sure did. Just not as loud as the 9x25.
