写的很详细，很多比如firepin safety和hammer block我都不知道有，这点跟现代手枪一样了，比rifle好． 至于trigger pull和精度我有不同意见，我的扳机测得是８磅，精度我４５码铁瞄无依托立姿可以打３寸靶，他说５０码８寸的散布我觉得可能是他的枪有问题或者人不习惯．
---- About 25 years ago when the British SASstormed the Iranian embassy amid explosions and gunfire, they made headlinenews around the world. And one thing in particular caught everyone's eye-theH&K MP5 carbines the soldiers were carrying. Exotic-looking and evoking aserious ability, those black carbines soon became the darling of the tacticalcommunity. When LAPD SWAT deployed them for the Olympics in 1984, the trend wasfirmly set-in order to be "cool" as a police unit, you needed MP5s. Fast-forward 20 years to today. While I'd like to think the"cool" factor isn't as important in purchasing police weapons, I fearit may still be so, especially when it comes to patrol rifles. Since the North Hollywood bank shoot-out, the move to rifles forpatrol has resembled a tidal wave of purchasing power. Some agencies haveacquired true long guns in .223 and .308 calibers. Others have elected to usepistol-caliber rifles and carbines. I need to confess I think if you're going to go to a rifle, you shouldgo to a rifle and bypass the stop-gap of a pistol-caliber carbine. But if yourcity fathers have deemed it politically correct or economically expedient togive you pistol-caliber carbines, you now have to make the best decisionregarding equipment. And even though pistol-caliber carbines are perhaps not theperfect solution, they are a move in the right direction. Any tool that allows an officer to deliver accurate, aimed firequickly and reliably is a good tool, and that's what most of the pistol-caliberrifles manage to do. If you think of them simply as a "better way todeliver your pistol's bullet" then you can keep things in perspective. It's important to remember, however, that while most loads willdeliver a slightly higher velocity out of these short-rifle barrels, manyactually won't. And those that do may suffer from some design shortcomings whenthe rounds disintegrate on impact at the higher velocities. If you're shootingpistol calibers in your rifles, make sure the ammo is designed to function atthe higher velocities of the rifle. A patrol rifle and/or a close-quarter SWAT rifle, needs to beshort, handy, and highly functional. There are many types that may fit theprofile, depending upon your specific needs. And now, Beretta has jumped ontothe train with the introduction of the Cx4 Storm Semiautomatic Carbine. Form and Function The Storm is marketed as a competitor to a number of other short,stylish patrol rifles. Looking like something you saw in the hands of those nastygorillas in the "Planet of the Apes" movies, the Storm is alightweight (5.75-pound) pistol-caliber carbine only 29.7 inches in length.That's a tidy package and handy to both tote and stash in the trunk. The Storm's unique design gives a shooter an enhanced-sightingradius (12.9 inches) and a shoulder stock, which means an officer can deliverhis or her pistol ammo where it's needed most. The Polymer construction (blue-anovel idea-or black plastic) means the basic stock of the rifle is tough andthe finish won't rub off like it would on a painted or coated stock. The16.6-inch chrome-lined barrel coaxes the most velocity out of any load. APicatinny rail on the top and sides lets you mount all sorts of lights, lasers,and other widgets (should that be your inclination) and you can even put avertical grip on the front to make it look even more like a space gun. At a street price of about $600, the Storm is right in theballpark with many of the other patrol carbine candidates and cheaper thanmost. So, it looks cool-with its neat, molded stock and sexy curves-can beswapped around to be completely ambidextrous, and can be changed from onecaliber to the other easily. Nifty. But, does it work? And if it does, howwell? All Sorts of Goodies Beretta put some thought into this one and tried very hard to makethe Storm an "everyman's" rifle. Sort of an "all things to allcops" way of thinking. They came very close, too. The take-down ispush-button easy (call that cop-proof), and the gun comes apart into threeassemblies that don't seem to lose any bits easily. More cop-proof design. A fixed-barrel design, a cross-bolt safety, a firing pin safety, ahammer block, and a handy widget that keeps the bolt closed if you drop it, aresome of the features of the Storm. The simple blow-back action means no gastubes or delicate parts to get clogged up with powder or lead residue to tiethings up. A loaded chamber indicator on the ejector is handy, and the rear recoilpad can be lengthened with inserts to increase the length of pull. It can beadjusted from as little as 12.35 inches to 15 inches. That's a really nicefeature for officers of all sizes. The Storm is available in a blue or black polymer stock and,frankly, I'd opt for blue just to be different. ("Why does everything haveto be black?" he asks in exasperation.) Its Picatinny rails offer versatility, and the front sight isfully adjustable for windage and elevation. The rear has a 50-meter and100-meter flip aperture. Both sights can be folded down in case you're usingoptics. Magazines are standard pistol mags from the Beretta pistol seriesand, depending upon the caliber, can be either from the 92/96 series or theCougar. Which brings us to an interesting feature of the Storm. It can beconverted from caliber to caliber. Some conversions require a different boltface, but the bottom line is if you go through that cycle all agencies seem tosuffer through, of changing calibers depending upon what you read in thepopular press, at least the Storm can stay with you with a barrel, magazine,and magazine adapter kit. The calibers available are 9x19 (standard9mm), the slightly longer 9x21 (What can we say? It's a European thing.), the.40 S&W, and the always-popular .45 ACP. Beretta is covering all of thebases. Really Nifty For all you southpaws out there, the Storm can be handilyconverted from right to left (or wrong to right, depending upon your point ofview). The charging handle, mag release, safety, and, yes, even the directionit ejects the empties, can be customized. Which means if you do convert your rifle to lefty, it probably hadbetter be your very own, so none of us "regular" people gets confusedif we check out an issue Storm and start reaching for all the wrong bits in thedark. Overall, the workmanship is typical of Beretta. Everything fitsnicely and the entire gun has that vaguely "European" feel that'shard to describe. It's sort of like driving a Fiat. It works the same as aFord, goes the same speed as a Ford, uses the same gasoline as a Ford, but it's"different" when you get behind the wheel. Ditto for the Storm. Allthose curves and such remind us of a high-performance Italian race car. As amatter of fact, Beretta actually hired a famous designer to make the Stormsexy. But with all its European fanciness, does the Storm deliver thegoods as a patrol rifle? Not quite. [url=]file:///C:\Users\ddeng\AppData\Local\Temp\msohtmlclip1\01\clip_image001.jpg[/url]
It was difficult to reach the magrelease button while maintaining a firing grip. Shooting Impressions While I can say the gun ran fine, digested all the ammo fed to it,nothing broke, and all the buttons and levers performed as advertised, that'sjust not enough to make this a great patrol rifle, at least not yet. With its outlandish curves, I wondered if the Storm would feel"right" when used in the real world. A quick throw to the shoulder ata trade show is very different from 700 or so rounds in the dust, heat, andgrit of a day at the range, or during the stress of training or a day on patrol. At the range, the Storm loaded as expected (10 rounds). The maginserted easily and locked home securely, but that's when I noticed the boltrelease was very hard to press down. It was also difficult (and impossible forsome other shooters) to manipulate with my firing grip in place. I all found iteasier to simply work the charging handle with the left hand (for right-handedshooters) to get the gun charged. Then it came time to release the magazine, and I found anothersmall problem. When I attempted to maintain a firing grip and reach around topress the mag button with the thumbs of my shooting hand, I found that Icouldn't quite reach the button. And you can't simply shift your grip (like ona 1911, SiG, or other gun with a mag release button to the rear of the triggerguard), since the stock cut-out doesn't allow your hand clearance to do so. I think you could change the mag release so you could punch itwith your trigger finger from the right side, and then get used to it. But I'mnot sure if pressure from your trigger finger lying alongside the grip whenfiring or moving in the field might accidentally release the mag. You'd have togive it a serious look before you did it for real. The trigger pull was hard-my RCBS gauge showed it at 10 to 11pounds-and a bit on the gritty side. In defense of the test gun, it is a veryearly sample, indeed only one of a few in the country, and I wonder if suchthings will be smoothed out down the line as Beretta receives input fromusers. The Storm shoulders well and is comfortable to shoot, fromstanding, sitting, prone, and the bench, and it seems to carry well. It's alightweight rifle and that will make it a patrolman's darling very quickly. I took 10 different 9mm loads with us and ran them through theStorm. The best 50-yard group (on an appropriate varmint target) was about fourinches, and was shot with the 95-grain PMC Starfire load. The 124-grain SpeerGold Dot came in right at its heels.

Groups from the bench were a bit of adisappointment and the 10-pound trigger pull didn’t help. Here, the author’swife, Suzi (a San Diego cop), tries out the Storm. I'll be honest and say I was a bit disappointed in the groupsdelivered. Some measured up to 8 inches at the 50-yard mark. All were shot froma bench rest. I had cleaned the barrel well before shooting, in case theprior tester had mucked it up, so we can't blame that. I think a more controllable trigger pull would help things and,frankly, being an early test gun, I'll bet things settle down as productiongets underway. To put things into perspective, I shot a 4.6-inch group the sameday using the Gold Dot at 50 yards with a Robar-modified Browning Hi-Power pistol. Final Thoughts Its light weight and its ease of carry are only two of the manypositive sides of the Storm. However, if my test sample was an indication ofhow the production guns fare, I'd lean on Beretta to do something aboutaccuracy, the trigger pull, and the ergonomics on the magazine release from afiring grip. All in all, the Cx4 Storm has some great potential once it getsover a couple of growing pains. Beretta
