This thing is an absolute BEAST! I bought the HK compensator for it, since I didn\'t feel like waiting until my 70\'s to get a suppressor. It was on my \"watch\" list, and when a few popped back into stock I grabbed one. It is a piece of history, and definitely an eye catcher. You\'re not carrying this thing unless you\'re Paul Bunyan, but if you need a portable Howitzer for self defense you\'ve got other issues going on. Like the 24K Desert Eagle .50, this is something you buy really for no other reason than to say that you have one...doesn\'t hurt that it\'s one hell of an accurate gun and durable beyond belief either.

I have big hands so this seems normal and everything else seems small. Even with this Mark 23, I wish the grip was a little longer. Whatever youve read about the Mark 23 if its good then its probably true. If you need a pistol with four levers on one side, its the only game in town. If you need a club to beat your enemy with should you run out of ammo - look no further. Should you buy one? Absolutely. Is a USP Tactical a good substitute? I guess. What year was it built? You can tell by looking at the two letters to the left of the serial number. A=0 B=1 C=2 D=3 E=4 F=5 G=6 H=7 I=8 K=9. So BK = 2019. (J is skipped). To the left of those letters is the German Federal Eagle sitting on top of the letter N or the letters CIP (Permanent International Commission for Firearms Testing) in lieu of the Eagle. The N stands for Nitrocellulose - the main ingredient in smokeless powder that was used in testing. Just so everyone is clear they didnt test it with black powder. The stag antler is the Proof Mark from the Ulm Proof House indicating that the barrel has been fired with 2 rounds that were 25 percent higher pressure than the barrel is rated for And it didnt blow up. There are 5 other major German Proof Houses that have different marks. A horse is one, a bear, and other code of arms symbols that to us look like shields. This is old school European stuff that they are still doing. The DE is the two letter abbreviation for Germany. The Mark 23 has been on my bucket list for over 20 years - longer than any other firearm. Imagine what finally checking that off was like. The ceremony contained all the pomp and pageantry you'd expect for such an event and the after party is ongoing. Reviewed By: James C on 10/19/2018 Rating: 5 of 5 Stars!

Fantastic weapon. You have to understand that this was one of the first handguns that was tested for SOCOM. Not only tested, it still is the most tested handgun on the planet. Yes, it is bulky. Yes, it is large. Yes, it could use an update, but this thing will shoot lights out with any ammo. So, if you have the coin, own something that can be passed to your kids as a collectors item back when people believed there could be an "offensive handgun." Cons- The Mark 23 was developed before there was a consensus on light rails. Unless you are willing to spend 2k on an Insight LAM that was designed for it, you will need an adapter. -Mags are pretty pricey, but watch Buds for sales. I picked up 2 for a decent price. -It is large. I think it feels larger than a Desert Eagle. That being said my wife, who is 5'1 can fire it without any problems. (She doesnt' feel comfortable firing the DE). Just get it. Shoot the piss out of it and put it in your safe. Reviewed By: Charles S on 04/30/2018 Rating: 5 of 5 Stars!

I have a mixed history with HK and the USP-patterned pistol. The third pistol I ever owned was a USP Compact and, to this day, was the worst pistol I've owned. The trigger was terrible and the slide release would eat in to my hand. The Mark 23, though, has quite a reputation, as well as undeniable good looks. Eventually, I gave in and gave HK another shot. Wow. This Mark 23 lives up to the hype. It is soft-shooting, accurate and comfortable. I know see my old USP as a bad scaled-down imitation of this Mark 23. I would buy it again in a heartbeat.

Nothing more to say than what hasn't been said in the other reviews. The Mark 23 is wildly accurate, beyond controllable, and an absolute pleasure to shoot. My wife has smaller hands and has trouble shooting her 1911 but when she shot this monster she actually really enjoyed it. I don't regret this purchase one bit. If you are on the fence with this one, rip off the band-aid and buy it. You will not regret it. Reviewed By: Thomas C on 09/21/2017 Rating: 5 of 5 Stars!

As usual Bud's delivery was on-time and communication was very good. And what can I say about the H&K Mark 23 SOCOM that hasn't already been said - nothing. It is a great pistol. Reviewed By: Douglas L on 09/19/2017 Rating: 5 of 5 Stars!

I'm a big, meaty guy and I like big, meaty guns. I love the feel of this pistol. It just feels like it means business. The large size means low recoil. I found a shoulder holster for it and carry it concealed sometimes. I told you I'm a big guy. There's no point in me telling you this gun is good. It's great. I'm sure you've read all about it. If not, you should. Here's what I will tell you. When you hold it, you will know you're holding a piece of history. When you bring it out at the range, people who know guns will whisper. Then they'll come over, hoping to hold it or even shoot it. Your friends will tell you to bring it when you go shooting. They will bring .45 ammo, so they can shoot it. Yeah, it's vanity, but sometimes that's the best reason to own something special. My Mark 23 sleeps beside me on the nightstand. There is no other gun I trust more to defend my home. I know it's expensive. Hey, I had to talk myself into it. But this might be the first gun I've ever purchased not feeling like I was taking at least a small chance on getting something that just wasn't up to snuff. If you love military weapons, and you want a piece of engineering art, you want this gun. If you have the money, you really can't go wrong. Did I mention this gun makes me very happy?

As always Buds service is great! Wow! This gun is awesome! I never thought I'd get one but I found one at a good price and figured I'd go for it. Everything about this gun is ridiculous but it's awesome. Very accurate with a certain elegance that only HK can provide. Reviewed By: Robert B on 02/22/2017 Rating: 5 of 5 Stars!

I purchased a HK MARK 23 from Buds in December 2016. Shipping was very fast! Before testing this firearm, I recommend cleaning and lubing it first. Compared to my other 3 HK .45 firearms, the MARK 23 is tighter and is a smoother operating pistol. So far, we've put a few hundred rounds through it. My adult Son would love this firearm in NYC but not allowed as of this date/time. His targets end up with a very large hole in it. His groupings are very tight. As for me, I'm older and doing great with this firearm. My groupings could be better if I adjust the sights but it's just too early. After I fire 500 to 1,000 rounds, I'll be at that point or the factory settings might be OK. I am just a little to the left and slightly down--trigger pulling issue--cockpit error sort of thing. But I feel it's a new pistol and I must get use to it. Show More Reviews
