9x23 / largo ammo question???

[1911crazy]

I just seen the winchester silver tip 9x23/largo 50rds for $37.52  its 125gr JHP @ 1450fps, they also had the winchester 9x23/largo 124gr JSP @ 1460fps, for 50rds at $27.19 i believe the prices are correct.  Seeing this kind of speed raises the flag that they maybe getting the 9x23 win and the 9mm largo ammo mixed up because both are 9x23 in size.  I know my LLama is the largest 1911 clone pistol i have ever seen in 9mm largo and the barrel is very thick in the chamber area too but i'm not ready to blow it up with the wrong ammo.     Its being advertised as 9x23/largo ammo?                  CZY but not that CZY

Crazy:  I wouldn't shoot that in a Llama 9mm Largo or any other 9mm Largo pistol.  The specs on that ammo are for the Winchester 9x23, not the european 9mm Largo (or 9mm Long, Steyr, Bergmann or Bergmann-Bayard).  FYI - back in the day when we didn't have much in the way of brain power and we could purchase any of the european 9mm Largo pistols for next to nothing, we would often make the mistake of loading 38 Supers to max and using them in these older european pistol until the pistols broke - most usually it was a extractor that broke and without parts available we would toss the piece and go buy a newer one. 

Until the 9x23 Winchester came out, the best of the 9mm Largo pistols was still the 1911 38 Super.  jmtcw.

IIRC, the Largo load was more in the 1200fps range (125gr).  About like a 38 ACP load (not the Super).

Airsporter:  You are correct.  Most European 9x23s, which are/were designated 9mm Largo, etc., usually pushed a 124-5 gn slug at around 1200'/sec.  The German 9mm Export which was fired from the C-96 Mauser Pistol, was the heaviest of the bunch with a 128 gn 9mm slug at around 1280'/sec. 

The 38 auto fired a 130 gn slug at about 1080'/sec.  When it was first introduced it's velocity was closer to current 38 Super loads but when the Super was introduced the 38 Auto was downloaded to prevent damage to older handguns.  Most 'white box' (plain jane) 38 Super ammo today runs around 1220-1280'/sec depending on maker. 

The 9x23 Winchester runs at around 1425'/sec, which is what the preferred load for many 38 Super shooters used to be usign 125 gn hollowpoints and Unique powder or if you perferred a Charles Askins load it would be a 115 gn hp and H110 powder for around 1500'/sec.   2 cents worth.

The case is the difference in modern 9x23's and is the weakest link in the largo's being loaded to moderns 9x23 pressures,

Well when i seen the ammo offered marked "9x23,largo"  a flag went up in my mind that we just talked about this and what will interchange and what won't.  Even though my llama extra 1911 clone is the biggest 1911 i have ever seen size wise i still won't interchange or try any other ammo put the spanish 9mm largo ammo.   My barrel and chamber are bigger than the 45acp barrels/chamber but i still won't chance it. I can see why some are mislead.

Having done a lot of work with the 9x23 using modern powders I can attest that the velocities achieved as shown would be over pressure for the 9x23 Largo.

Curious to know where you see that advertised.

I'll try to find the website again.  They listed it was 9x23 largo ammo new in the box.
 
I purchased a really heavy 1911 clone, a LLama extra in 9mm largo/38acp so they say.  The same dealer has another listed that shoot the 9mm largo/38 super too.  Same pistol as my a llama extra.  My barrel is as thick as the 38 super barrel i got from numrich.  Mikey did advise me the steel won't hold up on the llama with the heavier round so i gave up on that idea.  The barrel was $10 or so. I just may wait to get something with more power in a 1911.
