We are sometimes asked here at Ace Custom 45's Inc.: What is a "45Super"®
or in some cases why there is a "45Super"®?
While the concept has been written up many times in the past, perhaps
it will be helpful to those who are just becoming familiar with the
"45Super"® concept or
to those who have had some exposure to the "45Super"®
concept, to provide some background on the "45Super"®
, from its original conception dating back to 1988, to its current status
in 2000.
In 1988, the beginning idea for a "45Super"®
originated in Dean Grennells fertile imagination. Dean, longtime
managing editor of Gun World Magazine, envisioned the concept of updating
and strengthening of the popular Colt M1911A1G model auto through new
gunsmithing techniques and the utilization of modern cartridge cases
to improve the 45 ACP!
To do this Grennells went straight to the problem, pinpointing
the weakest part of the M1911 system - the cartridge case itself! The
standard 45 ACP leaves a significant portion of the case hanging unsupported
over the angled feed ramp of the barrel, thereby limiting pressures
and velocities to low levels. The unsupported section is forward of
the case head and the brass there is thin, this poses no particular
problem since the standard 45 ACP is loaded to levels not much greater
than black powder loads, and standard brass is amply strong to handle
this! However this scenario does present a serious barrier to increased
ballistic performance! (There are some who would argue: that there is
no need for increased ballistic performance for the 45 ACP, for those
who are of that mindset we leave them there!)
To address the case weakness of the standard .45 ACP
Grennell used a modified .451 Detonics magnum case. This case was longer
than the 45 ACP, with thicker walls and a heavier web area to withstand
higher pressures. These cases trimmed to proper 45 ACP length and then
inside neck reamed to accept 45 ACP bullets, provided the basis for
the "45Super"®!
As a matter of note it was never intentional by Grennell
nor is it ours, to wring the last foot-second from a 45 ACP pistol,
but to provide a performance boost for 45 auto fans without resorting
to extensive and expensive modifications! Grennell did this with the
shortened .451 Detonics magnum case utilizing principally a standard
.45 auto government model with a 22 lb. recoil spring. While he was
satisfied with the cartridge concept, the pistol clearly needed some
work to refine the concept completely.

"Gun World" staffer, who brought a sackful of .451 Detonics
brass and a Colt .45 Auto to Ace Custom 45's Inc. This lead to a series
of upgrading modifications to the Colt .45 Auto that eventually lead
to a properly functioning "45Super"®
pistol. The original loads were chrongraphed using both 185 and 230
grain bullets and the velocities returned were impressive indeed. (Detonics'
magnum cases)
185 Gr @ up to 1400 FPS
230 Gr @ up to 1200 FPS
At this point Bruce Hodgon of Hodgon Powder Company Incorporated was
contacted and agreed to run pressure tests for the "45Super"®
and thanks to his gracious efforts, pressure tests revealed that the
Colt Mod 1911A1 was well within the strength compatibility required
by the "45Super"® pressures. Maximum
working pressures for the .38 Super (for example) is 35,700 CUP; most
of the loads ("45Super"® ) tested by
Hodgon were slightly below this level! (By contrast our top "45Super"®
loads today, generate about 28,000 CUP! 185 Gr @ 1300 FPS 230
Gr @ 1100 FPS.)
It had been done: the "45Super"®
was now a reality! Ace Custom 45's added to its line of services "45Super"®
conversions on customer supplied weapons!
Eventually the supply of .451 Detonic's Magnum cases
dried up and except for laboriously modifying .308 Winchester rifle
brass there was no cartridge case suitable for the "45Super"®
concept.
This changed in 1994 when factory produced "45Super"®
ammunition became available and Ace Custom45s obtained a "Federally
Registered Trademark" of the name "45Super"®. The
factory "45Super"® ammunition was based on "new cases"
made by Starline Brass to meet the parameters required for "45Super"®
pressures and velocities; with the cases being headstamped "45Super"®,
and finally Springfield, Inc. introduction of a factory produced "45Super"®
PISTOL, their V-16 LONGSLIDE "45Super"® pistol.
Currently Ace Custom .45's Inc. offers 10 different
complete "45Super"® pistols, based
on Springfield Armory, Para-ordnance, Kimber, and Glock Model 21 units
and of course we continue to offer "45Super"®
conversions on customer supplied weapons, as well as "Gunsmith
fit" "45Super"® conversion
kits, for Govt. Mod 1911 style pistols and 4506 series Smith & Wesson
pistols, and the Glock M-21.
As for the future; Ace Custom .45's Inc. is currently
evaluating other candidates for the "45Super"®
concept, and will be adding new additions to our current line of complete
"45Super"® pistols in the future.
