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 other modifications. While you can shoot 45 SUPER out of some stock 45 CP +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.

I bought this ammo in preparation for my trip to the Northwest, Canada and then Alaska. I could not drive through Canada with my 44 magnums because they were like 1/8" too short to legally drive through Canada with. So I took the advice I got from others and converted my G21 to shoot the super. All I did was buy a KKM barrel and switch out a 25lb spring from the 22lb spring I used for the P 45 Outdoorsman. I ran several magazines of the 45 Super Outdoorsman and the 45 Super FMJFN and I had no problems with either so I decided to go with the 45 Super Outdoorsman. This is by far the most powerful semi auto round I have fired or even heard of. This round is more powerful than regular 240 44 mag ammo out of my 4 inch barrel. I have Garrett Cartridges and a few of the other Buffalo Bore 44 mag loads and although the 45 Super is not as powerful as them, I feel just as confident using the G21 with the 45 Super Outdoorsman. I would rather have had my 44s, but after many practice iterations burning through about 7 rounds in 2 seconds, with 7 more rounds to spare, I was feeling confident. confident to just walk the trails and walk around with my dogs that is. not hunt or anything. I just wanted to be able to give myself a chance if anything happened. Don't let anyone tell you that you won't have a chance with this 45 Super. I stopped quite a bit on my way up to Prudhoe Bay on the Dalton, but I never went into any deep remote areas with limited visibility due to brush. One time I stopped and was going to let the dogs out and the dogs went nuts for some reason. They are APBTs and rarely ever bark or growl and they never got that riled up and never have till this day. I had one leg out of the truck and pulled it back in and drove off, 100 yards down the road there was a huge Grizzly chilling out. and that was the extent of my Grizzly encounters. Skunks have always been my #1 Arch Enemy!!

With a 23lb recoil spring in my Springfield 1911, the recoil of this round was that of a lite recoiling 10mm. It was easily the most accurate .45 caliber bullet I've ever shot with point of aim being exactly the point of impact at 25 yards. This is my go to round when Kayak fishing with black bears, boars, and two legged creeps around.

Shot it out of my glock 21sf with lwd 6in barrel and ismi 22lb spring, stainless guide rod.
Recoil increase is 30%, measurable increase in muzzle noise, over 50% increase in downrange performance.
It recoils like a hot 357 mag, but hits targets like a 44 mag.
Seriously considering it as a primary hunting handgun.

here's a video of me shooting it:

Friends and Customers, 08-18-20


All shooters are being inconvenienced with what is happening to our society and the rush it is causing on ammo supplies. We have LOTS of ammo in stock and are making more at a huge volume on a daily basis. If our web site allows you to order any item, that means it is in stock—WE DO NOT TAKE ORDERS FOR ITEMS WE DO NOT HAVE! So, please do not email and ask if items are in stock. If they aren’t, the shopping cart will not take your order.

We have hundreds of customers to get orders to on a daily basis. In order for us to accomplish this for our customers, we ask the following.

  1. Be sure of what you are ordering. You are going to get what you ordered.

  2. Do not contact us and ask to change an order you’ve already placed. When we manually change orders it requires a lot of time that we do not have during this rush and it keeps us from serving all of our customers. If you’d like to change an order, we can no longer do that till things slow down, so simply place another order for more product, but PLEASE, NO MORE CHANGES after the fact!

  3. We NEVER have and never will take ammo exchanges or returns and then turn around and re-sale that ammo to unsuspecting customers as factory new ammo—this is not safe nor is it fair to customers who are buying what they think is new and safe ammo. No ammo is tamper proof! So please stop asking to exchange or get a refund for ammo you ordered, but have changed your mind about.

  4. Please do not contact us and ask for tracking numbers or “when will my ammo ship”? Our system automatically emails out tracking numbers on the orders we ship each day, however, because these emails are coming from a corporation shopping cart, many of these emails may go to your spam folder……..please look there. If it is not in your spam folder, that means we have not yet shipped. At current order rates, we are shipping within 5-7 business days of the time an internet order is placed. Please sit tight. Your ammo will arrive at the same time if you track it or not and will certainly arrive later if we are swamped answering questions instead of getting orders shipped. When 30-50 people per day send emails asking for tracking information and we have to pull that information up, then type it out and email it, it takes a huge portion of our work day that we should be using to ship those orders to customers in need. Please leave us alone so we can serve all of you. (ship to you) It’s a bit selfish, during times of shortages, when so many folks need to protect their families, to slow us down because you ordered carelessly or want to change your order. Right now, we expect you to do your part to help us all get the ammo we need in our troubled country.

These measures are hopefully temporary and will not be needed for long as we enjoy the interaction with our customers, so please, for the time being, be mindful of all those others who are also trying to get ammo during what I think is a societal meltdown/emergency. Hopefully, we can serve you all. We want you and your families to be armed and safe and we wish you the best during these trying times. My biggest concern is that things will worsen yet more, for a while. Until things straighten out in our government and society, we will have to streamline our customer service in order to serve all customers. Thank you for your understanding.

Good shooting and God bless,

Tim Sundles
