    Shot one of these today and I was left a bit let down. The hype I had in my mind was not on par with what I experienced. One thing is for sure though, the gun does manage muzzle control EXCEPTIONALLY well.

    The recoil and overall feel of the gun reminded me of the HK UMP, but the muzzle exhibited 25% of the climb even with a quick cadence.

    Still a unique gun, and I'm glad I got the chance to play with it.

    1911 where'd you get to shoot one of those beauties? It is kind of disappointing to hear that they don't live up to their reputation through testing... I have to disagree with Code... I think they are beautiful works of art... they also look highly concealable for exec transport...

    At work. Some kid bought one from a local gunstore, waited forever for it evidently.

    It's a neat gun, just not up to the hype in my opinion. It really didn't fix anything. The MP5 delivers 28 rounds in a single grapefruit sized hole at a controllable, but fast, RPM. It's lightweight, rugged, adaptable, and has been proven in it's designed role time after time.

    The only adaptation to sub-guns today is the machine pistol style of compactness, which isn't really an adaptation so much as a choice, and the chamberings favoring small, lightweight, armor piercing munitions like the 5.7x28 FN and HK's 4.7mm. I personally might question the lethality of the round, but knowing that the P90 can deliver 10 of them in the same hole at close range in a single second kinda makes it a moot point.

    Good to know... yeah I was looking around the other day and saw that they are in most of the mags for the 2009 buyer's guide and thought they were a pretty reasonable price online... especially if they reduced recoil etc like they promised... since I was a kid I've always loved the look and feel of the MP5... I can't decide though between the Kriss the MP5 and the USC... any ideas?

    MP5 is by far the better choice in my opinion.

    You have to remember that you're talking a handgun round in a rifle-ish size package. Recoil isn't going to be the issue until you go full auto.

    Now if it were chambered in .308, that would be something!

    I'm giving serious consideration to a 9mm AR 15.

    I'm giving serious consideration to a 9mm AR 15.

    Of the choices the MP5 is clearly superior in control in full auto. It's not just the 9mm round, but the butter smooth action of the MP5 that set's it apart. I've shot other sub-guns that really are either too fast, or have actions that beat the gun around when you shoot it.

    The HK UMP .45 is a clear example of the latter. The gun dances in your hands regardless of how proper or tight your grip is. It's like you are shooting an old WWII era gun. In fact, when I shot a full-auto Riesing I got flashbacks to the UMP. The Riesing was compensated and it still walked alot. Maybe it's me, I'm just a regular Joe, but the mark of a good gun in my opinion means it doesn't require a full blown Delta Operator to utilize functionaly. One thing I will say about the .45 sub-guns is they put alot of lead mass into a target. I don't question their lethality.

    The second being the chainsaw era of "how fast can this thing shoot?" sub-guns. The Mac11 I shot is a class example of this type. You could cut a fruit stand in half in 0.002 seconds with this thing, but to hell with actually putting accurate full auto fire on something further than 10 - 15 yards. Granted, the gun was designed for that purpose ... so I can't fault it in that regard.

    In the end, the MP5 is still there... it's the 1911 of the sub-gun world. It's the old dog of the crowd and it still is at the forefront of the game on un-armored targets. Nowadays the prevelancy of effective body armor, and the demands of the market have either replaced the MP5 with M4s or the new school P90 / MP7.

    For what it's worth, my perspective is a bit different: I ran an AK at tactical rifle (run and gun) matches in CA for about a year and a half. If I can keep an AK in 7.62x39 under control for rapid fire (without a pistol grip!), I'm definitely not worried about a handgun caliber. FA is probably totally different, but I've got little urge to do much more than try it out. As a "tool", I only a very limited use for full auto.

    A friend of mine talks about being trained on various subguns. First one was the MP5, since that's what he'd be using whenever he needed to use one. Then they moved on to things like the Uzi, Thompson, PPSh, etc. for familiarization across a broad range of firearms he might experience.

    He's actually kind of bitter that they had him shoot the MP5 first, because it completely ruined the Thompson for him.

    Control is relative.

    The MP5 is like an AR15 compared to the AK47 (UMP45). Very similar differences between the two. Neither is uncontrollable, but I think just about everyone will agree that the AR15 is much smoother. It's the same story with the MP5, in my opinion.

    I personally disliked, and was somewhat let down by, the UMP. It was fun and it's kinda unique, but it just left me thinking... how could HK build the MP5, then put out this?

    Our local pd just got rid of all their MP5's, wish I could have bought one but they brought them down to our shop then cut them in half and sold them to some guy for $800.00.

    "Because we're H und K: We hate you.... and you suck."

    The AK just needs a little tuning to get it running smooth. The recoil spring is too light, and they need a real brake on the front. Slant compensators suck.

    Got the chance to handle a HK USC at Sportsman's Finest and I really liked the design of the piece and the weight of it but was really turned off by the ultra-lightweight polymer stock... it just didn't seem like it would absorb the shock of a .45 round like an AK's stock or an AR's Stock would...

    There should be less recoil from a .45 ACP.

    A quick Google search suggests that .45 ACP typically makes around 400 ft-lbs of energy at the muzzle. Let's say 500 because of the longer barrel.

    .223 Remington (slightly less powerful than the 5.56, but close enough for now) clocks in around 1600, about 3 times as powerful. 7.62x39mm is around 1500 ft-lbs.

    These all depend on barrel length and the particular load.

    IMO, AK stocks do a bad job of managing recoil. The butt surface is never flat enough, but is gently curved leaving a nice sharp corner at the bottom to bite your shoulder.

    Good insight and definitely something that I have noticed about AK stocks

    There's more recoil in a .45 caliber carbine than a .223 Remington AR.

    The .223 runs off of a long, cushy cycle and is a low grain weight round. The .45 operates with a large block in a blow-back operation. That is the main difference; there's so much inertia in the system that it pushes the gun around.

    Nevermind the fact that .45 does not compensate very well due to the low pressures.

    True and the .45 doesn't funnel the gasses through the barrel initially like the .223 does... it blows back and then forward after rebounding off of the operators wrist or shoulder...

    Recoil from the round really requires a decent grain count. Calibers like .22-250, .204 Ruger, .223 Remington, etc. have good kinetic energy due to the velocity, but very little recoil.

    FN 5.7 is another example of this... especially in pistol form. The 5.7 shoots like a .32 Auto in terms of felt recoil, but caries the same kinetic energy as a normal 9mm loading.

    Shooting a wide variety of calibers in bolt rifles and even various grain weights and loadings in the same calibers will open your eyes up to alot. Generally speaking, the energy produced by the various calibers does not give you it's recoil characteristics.
