The HK Mark 23 Caliber .45 ACP pistol gives shooters match grade accuracy equal to that of the finest custom made handguns — yet exceeds the most stringent operational requirements ever demanded of a combat handgun. The Mark 23 provides this accuracy without the need for hand-fitted parts common in custom-built match pistols costing thousands of dollars more. One of the most thoroughly tested handguns in history, the MK23/Mark 23 project originated in 1991 when HK began development for the U.S. Special Operations Command, the organization that directs the activities of America’s most elite military units, including the Navy SEALs and the Army Special Forces. On May 1, 1996, the first HK MK 23 pistols were delivered to the U.S. Special Operations Command for operational deployment, making the MK 23 the first caliber .45 ACP pistol to enter American military service since the venerable Government Model 1911A1. During testing, MK 23 pistols met the most stringent operational and accuracy requirements ever demanded of a combat handgun. Endurance testing demonstrated a service life of over 30,000 rounds of +P ammunition. To meet the reliability requirement, the pistol had to demonstrate a minimum of 2,000 mean rounds between stoppages (MRBS) with both M1911 ball and +P ammunition. All pistols exceeded the 2000 MRBS with an average of 6000 MRBS. In more than 450 accuracy test firings from a precision firing fixture at 25 meters, MK 23 pistols far exceeded the government requirement, averaging 1.44 inches, with 65 groups of less than one inch. There were four groups of .5 inches, with 5 rounds going through the same hole! The Mark 23 is available in .45 ACP

I purchased a Mark 23 last year after extensive research and handling. While I\'m content with paying for Heckler & Koch products, I still find it reasonable to shop around, especially when I know what I\'m looking for. All things considered the Mark 23 is an absolute work of art, truly a great handgun (large). I enjoy shooting the Mark 23 so much that I decided to buy another as an investment piece.

The handgun is more than 10.0 inches long, however it is not as heavy as you may think given the outstanding balance to the design and the use of polymers.
Most handguns are excellent out to 25 meters, the Mark 23 will shoot 1-2 inch groups at 50 meters with very little effort beyond the basics.
Design is hearty given the intended customer, it will outlive the owner, perhaps by a few generations.
Built on P ammunition, meaning your regular .45 ACP will be even less than what was expected in terms of pressures (resulting wear).

- The Mark 23 is not intended to be concealed in normal dress, it is a duty/operational handgun for a rig or open carry via holster.
- Not a cheap firearm, you have to pay for the experience and opportunity to own one.

Highly recommended for HK buyers, polymer handguns buyers looking for a .45 ACP, or those looking for a rock solid handgun for the most difficult conditions.

Great transaction with Bud's again. Awesome HK pistol with the reliability you would expect. Very accurate with all types of ammunition. My friends love when I bring this thing to the range. A tad expensive but I consider it money well spent.

Great pistol. People say this is a huge pistol but when they hold it they are surprised it isn't that big. When they shoot it, they go looking for one. This is the most accurate pistol I've ever shot, others say the same. It doesn't kick, my wife is expert and shoots 9mm and says this has less recoil. The Bud's price assures you it will retain it's value. It's well worth the money and you won't be upset. I'm around Navy Seals and Para Jumpers quite a bit and they tell me how great this pistol is, they all own one.

A tad expensive, but worth every penny. Now I know why they call this firearm the "Zombie Slayer"! Not because I let out a fart every time I shoot it, but because of its enormous power behind each shot. I would marry this firearm, if only it was legal to marry pistols in the state of Texas, but it is not, so I guess I will just stay with my wife.........for now.....this gun is a collector's gun, and soon to be a collector's dream!

$1,707 is a closeout price on an investment grade pistol. These are a beautifully made gun. That description may sound odd for a mostly plastic and stamped steel firearm, but it is beautifully crafted. It's big, accurate, and arguably impractical, but fun to shoot, ultra accurate and reliable. Simply put, if you have the means, it's a must have pistol, be it for use as a shooter or stash away and make a tidy profit from a rabid HK collector a few years down the road.

Really great gun, buds was solid as always with their quick delivery and it was in perfect shape as usual. Low recoil for a 45, and quite accurate if you can shoot. It's a good sized pistol for sure, but well balanced. 2 thumbs up!! I farted too!

Best shooting pistol ever made. It's noticably more accurate than other pistols. A true suppressor host, and literally indestructible! A must for any HK collector.

AWESOME-BIG-MONSTER-OF-A-GUN. Really hold one first before buying. I would have been better off to spend the cash on three Glocks and a few extra mags. This was to much stress for $1834. I'll re-gift this zombe-slayer+_+

$2k for a polymer pistol, was I crazy to buy it? No! This gun will put bullet on top of bullet (if you do your part). Everyone is quick to knock the size but at 6'6" 260 pounds this gun is perfect (for me). Recoil is unbelievably light for the .45 ACP round and crazy quiet suppressed. The Silencerco Osprey looks as if it were made for the gun. I like this gun so much that I actually bought a second one! HK's are better than $ in the bank. This is comming from a guy that emptied his 401k and pension to invest in "Black Gold" guns. For years the rumor has always been that HK was discontinuing the MK 23. I have a dealer friend that was at Shot Show 2011 and the HK rep stated, "We have about 40 left at the factory and that is going to be it, other than the ones already at the distributors and dealers". If you want one get it now!
