    I'm curious why so many military personal use the G17 (IDF for example) but most North American police forces use the G22. Is the attraction of the G17 shooting accuracy and controlability?

    well since they are the exact same size demensionally, and have the same barrel length, the only accuracy differences are going to be in caliber differences. I would think that the G22 would be more accurate because the .40s&w is a more accurate cartridge, heavier, slower bullets are going to be more accurate. so a 180gr flat nose .40cal slug going 850fps SHOULD be more accurate than a smaller, lighter 147gr bullet going 1000fps. just my thoughts. keep in mind that the human is the ultimate variable, both pistols side by side in a mechanical shooting machine would probably yield nearly identical accuracy

    Actually the 9mm is inherently more accurate than the .40 S&W.

    Cost of ammunition also has a bit to do with it. Depending what dealer and supplier you buy from, you can get a 1,000 rounds of 9mm for around $200ish.

    I believe the G17 is more accurate though and I am a .40 fanboy.

    We shot G17s in the police academy and even though we only put about <500 rounds a piece through them I noticed they were a tad bit more accurate. I CCW a Glock 23 Gen4. I am a pretty damn good shot with it, but I am a tad bit better with a 9mm.

    As for LE using the .40, its a compromise between the 9 and the 45. It mostly has to do with cost. There is a pretty decent distribution of Departments using 9mm and .40, very few departments use 357SIG and 45ACP. In fact, I think in a recent article in either Police Magazine or American Police Beat, there was an article about a department downgrading from 45 to .40 due to cost.

    The 9mm is a NATO issued round, maybe that's why more military personnel use it. It's always been the favorite round in European armies and the 45 ACP, in the USA.

    Cops use the 40 S&W over the 9mm because it is a more powerful round, usually. That's why I like the 40 and 357 sig, over the 9mm.

    My 22 Gen 4 is very accurate

    I always shoot 9mm more accurately all else being equal, regardless of the platform.

    Basically the 9mm is the cartridge that most like and use.

    My guess would be that if one had a Ransom rest and a bunch of pistols that there would be more differences in accuracy between individual Glocks regardless of caliber than there would be differences between groups of G17s and G22s compared to each other.

    The .40 S&W was created as the "standard" FBI round. Once the FBI adopted it, other law enforcement agencies followed suit. However, even though S&W developed the round, Glock beat them to market with the G22.

    No. 9mm has nothing to do with being a preferential round. Except in the area of cost. It's a NATO thing.

    I think it is. I have been trying to convert from .40 and back to .45 and 9mm for their less recoil and better accuracy

    I don't think it would be fair or logical saying one is more accurate than the other. I would say it depends on who's shooting. I dont want anybody to take this the wrong way. Its just my thinking.

    Actually, 9mm has everything to do with being a preferential round.

    Accuracy, however, has nothing to do with it.

    It is prefered in worldwide military service because it is by far the most common pistol round in existence, serves admirably ballisitically-speaking and is less expensive and lighter than the larger calibers. All of these contribute to it being "preferential" and in addition, in FMJ persuasion is utterly the equal ballisitically to the larger service pistol rounds. And FMJ's is all that matters in military service. Yes, it is also the NATO round which means member nations' military forces will continue to use it.

    Even in JHP form, the 9mm has certain advantages over the .40 and .45 and to some degree they over the 9x19, with all being so similar in terminal performance it is hard to argue one over the other from that perspective.

    The .40 got a jump start among police forces in the late '80's for a number of reasons, became well-entrenched and has thus served as the "standard" US LE round since then.

    Will be interesting to see if the cost issues allow the 9x19 to gain any ground in the next few years, but I sort of doubt it for the most part. .40 is dug in pretty deep logistically at least as far as LE is concerned.

    This question is answered in the hands of the shooter.

    basic mechanical accuracy, as another poster mentioned is for practical purposes the same across all models/sizes/calibers of glocks. in general however a larger number of people can find the 9mm easier to shoot accurately. So lets say in a machine rest the guns will be the same. in shooters hands usually the 9mm will be more accurate but that is a function of the shooter not the gun really. I myself shoot a 9 better than a 40- I've been shooting pistols for 30 years or more and made master in gssf last year,so I can hold my own with just about any pistol, but do have better reuslts with a 9.

    The .40 has more recoil so people tend to be less accurate.
    If you put both guns on a block, they properly shoot the same, with the .40 being 1mm larger.
    The the handgun round for military is the 9mm while LE sees them largely as too weak.

    Police also have to deal with crackheads and people loaded up on PCP. Military, not so much.

    A friend of mine in Macon PD stated that the reason why his department uses .45 GAP is for better possibility of one shot stops. His example being that if you have to use your firearm with in arms reach of some one, one shot from the .45 GAP has a better chance of ending it over the .40 and 9mm.

    Generally speaking when it comes to accuracy the 9mm is a more accurate round. Same equation applies to 5.56 (Accuracy & longer range) vs 7.62 (More stopping power, less accurate, less range). That's my understanding at least.

    You could probably argue that both rounds are equal in accuracy up to a certain range. But at longer range the 9mm wins because it has higher velocity and is a smaller round, which means it has less drag as it travels.

    I have 5 Glocks including a Gen2 G17 and Gen4 G23. I shoot the G17 the most accurately of all my Glocks. On a good day, I can plop 5 rounds into 1" at 15 yards slow fire. The Gen4 G23 I have, needs some trigger work to be comparable to the G17, but it's more accurate than my buddy's Gen2 G23. I've read that w/ the dual recoil spring assembly, it allows the action to stay closed a smidge longer than previously, allowing for more accurate shots. I would venture to guess that all Gen4's are more accurate than previous Gen's and that the G17 would still be a smidge more accurate than the G22.
