super vs supercomp vs 9mm

I bought an older bianchi shroud with movermount and an Aimpoint comp. the good thing there is an older SVI bolted on to it :D

 

It is chambered for 38super, I have not seen it in real life so I don't know how the barrel is. If the barrel is good I would keep it in .38.

I have no brass so should I go for super or super comp brass?

if the barrel is not capable of descent groups I can fit a new barrel and I can go 9x19 (or 9x23)

double stack guns must use 38 super comp brass or feeding problems will occur.  the head is rebated slightly on super comp.  therefor extractor tuning is critical for proper function.   That said with proper maintenance and tuning they run fine.

Many competitors only load 7 or 8 rounds in their magazines, so the SuperComp vs Super debate is somewhat redundant. 9mm can shoot just as accurately as either Super or SuperComp.... The Super length cartridges are marginally less troublesome in general, but any of the 3 are fine. It comes down to availability of supply and cost.

You can shoot 9 x 23 in a Super barrel but I don't recommend it.  Its obsolete and brass is difficult or impossible to find.  I shot it for years and have a 95 gr. steel load if interested.

I'm still shooting it. No problems getting brass. I even get my brass handed back to me. Lol

yesterdat the first test... first load was just the minimum load of N320 with a 115gr Fiocchi FMJ. gun worked fine and +- 2" group ofhand at 25m. the standard STI trigger is way to long for me so I have to fit something different (Geppert Vario trigger)

 

I've cleand the comp and put a new barrelcrown on the barrel... there where some "cleaning marks" on the barrel...

 

now I have some .357 127gr TC bullet for test 2 (plated H&N bullets from Germany)

Not true, I’ve ran 20,000+ 9mm loaded out to 1.150” without any issues... many here have no issues at all when the gun is built correctly.
