ITEM 45S255

45 Super is externally/dimensionally identical to 45 acp or 45 ACP +P and is designed to be used in 45 acp semi-auto pistols that have been fitted with stronger than normal recoil springs and a shock buffer, plus a couple of other modifications. While you can shoot 45 SUPER out of some stock 45 ACP +P pistols such as the Glock 21, HK USP, or the full-sized all steel 1911, you will batter your pistol if you do not have them modified to handle the extra pressure and slide velocity of the 45 Super.

All our 45 Super ammunition is loaded with flash suppressed powders so that if you have to fire in low light (when the criminal element is out) you will not be blinded by your own gunfire at the worst possible moment. 

To learn about the modifications your 45 acp pistol needs to reliably and safely fire 45 SUPER, contact Garey Hindman at 936-402-3484. Garey is the foremost authority on 45 Super modifications/conversions for your 45 acp and Garey performs such conversions for a living.

The below velocities were fired from my Colt Gold Cup Govt. Model (5-inch) that was converted by Garey.

1,330 fps -- Item # 45S185 - (185gr. Jhp)
1,235 fps -- Item # 45S200 - (200gr. Jhp)
1,131 fps -- Item # 45S230 - (230gr. Jhp)
1,133 fps -- Item # 45S230FMJ - (230gr. FMJ-FLAT NOSE) 
1,090 fps -- Item # 45S255 -  (255gr. HARD CAST-FLAT NOSE)

As always with Buffalo Bore Ammunition, we use real-world firearms to give you real-world data and results.

All three of the JHP loads were designed for anti-personnel use and for hunting small big game-like deer. The two solid bullet loads were designed for breaking large bones like a bear's shoulders or skull but will work for anti-personnel use as well if you need to shoot through cover like car doors or stick frame walls.

This round will chamber and fire reliably from a H&K USP 45 Tactical and will deliver substantial recoil compared to 230 grain standard 45 ACP loads. Such stout ammo will require a good deal more training and familiarization, but delivers performance unmatched by any other auto handgun ammo. Only 10MM or custom guns in 460 Rowland can compare.

Converted my Springer 1911 "Loaded" to .45Super. This ammo is the most accurate handgun round I've ever shot in my 25 years of shooting. It also chrono's a hair over 1100fps out of a 5" Springfield 1911. This is truly a woodsman's load that is at the entry level of .44magnum. The difference is much faster reloads than a wheel gun and much more firepower being used in a semi-auto platform. Best yet, it only recoils to that of a .45acp P load when said 1911 has the proper 23lb recoil spring along with a quality recoil buffer. This along with upgraded "extra power" magazine springs and you have a .45Super that is every bit as reliable as your trusted 1911 in .45acp.
