IMO - with the additional S&W 625 PC being offered with aHave shot the 3", 4", 5", and 6" versions; ideal 10mm platform.
But I have no idea why a "3 7/8""......
I have a .400 CorBon barrel for my 1911. I got it from Jarvis Inc. Hamilton MT It is a "Drop-In" Peter Pi came up with the .400 CorBon cartridge in
1997. It is a necked down .45 ACP to .40 with a 25 deg. angle shoulder. Note: on Jan 1 2000 I believe Corbon changed the case to use a small pistol
primer instead of the large pistol primer used in the .45 ACP case. I have heard that some loads/powder/bullet weight combos use small rifle primers and others use small pistol primers, why I do not know and CorBon ain't telling.
CorBon has not submitted .400 CorBOn to SAAMI for their blessing but some
estimate that it is loaded to around 26,500 PSI vs standard
.45 ACP 21,000 .45 ACP +P 23,000 but even so it is way below
.40 S&W as well as 10MM AUto pressures which are in the 35,000 or
more pressure ranges.
.400 CorBon has the advantage of being able to switch back and
forth tween it and .45 ACP. I think 10MM AUto with the long straight
case gains advantage over the .400 CorBon as well as .40 S&W when iit
comes to heavier 170 DPX, 180 & 200 grain bullets due to the short neck
of the .400 CorBon and the short case of the .40 S&W.
I'll probably keep my steel frame 1911 as a dedicated platform for the
.400 CorBon and get another S&W 1911 with the scandium frame.
I think CorBon ammo a bit spendy and found the following loads at
