Pistol calibers similar to 5.7 in capability?

    Are there any other rounds that will perform similarly or better to the 5.7 out of a pistol? I'd like to pick up something CCW-able that will have the distance capability and penetration of the 5.7 without upgrading to something in the size and weight of the AR/AK pistols.

    I've already got a .460S&W Mag, and while that would kill whatever with the sheer impact/force and it has distance it's also got a limitation of 5rds. and a pretty stout recoil.

    Any thoughts on a semi-auto pistol that would be more powerful but in the arena as the Five-seveN?

    Thanks!

    10mm would be closest to flat shooting distance auto in my mine followed by the 357 SIG. 5.7 is a joke of a round, CF 22 magnum that costs a hell of a lot more. Yeah I know everyones cousin knocked over a moose with one last year, still lame.

    CZ52 or Tokarev in 7.62X25. Ruger P89 in 30 Luger.

    The only reason the 5.7 is not a viable option is because it has never picked up mainstream acceptance. It is a great round but impractical, especially for pistol use due to the limited/expensive ammo.

    For semi-auto, .357 SIG is your best bet for maximum performance. It is a bit expensive but you have many ammo options and can practice with .40 S&W; it shoots very similar. You can also easily swap between the two calibers with one handgun.

    Not sure what 30 Luger is and can't say I've ever seen a P89 in that caliber.

    However, I forgot about the x25... that stuff is H O T!! I know I saw youtube vids of it going through both sides of a vest like a hot knife through butter.

    Only problem with all the x25 guns is that none of the pistols I've seen have decent/adjustable sights on them.

    Thanks!

    10mm is not that flat shooting of a round. 9mm +P and .357 Sig go a lot faster. Along with the 7.62x25 and 30 Luger.

    Don't forget the 9x25 the .38 supper and the 9x21.

    You must be smoking the good stuff because I have never seen a 22 magnum hit 5.7 velocity out of a pistol barrel. :faint:

    7.62x25 is about the cheapest ta get,then find a competent smith ta put decent sights on it.I prefer the Tok over the Mak.'08.

    <<-- Does carry a Norinco Tok and I don't feel under armed by doing so.

    Really? I have a pet load that throws a 135 gr. 1700 fps average (w/chrono @ 5y) in the 10mm out of a 4 1/2" barreled G29. None of these other rounds are throwing as fast as that even with the longer barreled pistols they are chambered in.

    By the way...That's 866 fpe compared to the 358 fpe the FiveSeven has.

    I have not clocked 5.7 ammo from the fiveSeven pistol, but it likely will go much faster than .22 mag out of a pistol barrel, and possibly even faster than .22 mag out of a rifle barrel. One thing is for certain, .22 mag out of a pistol barrel is quite slow, and really not much more power than .22lr out of the pistol barrel (which based on my use of the chorno and my AA conversion kit with a 3.8" barrel, you're looking at around 85-90 foot pounds of energy using .22lr). Of course, it is still lethal...

    The FiveSeven pistol is a cool design, but I would much rather see a slightly larger diameter projectile shot out of it. 7mm would be better for a intermediate field caliber.

    Sure if your hand loading to the high end. Factory 10mm ammo doesn't do that.

    10mms have higher velocity than 9mm or .357 SIG on factory loads but I do not get why some people think it is the holy grail of semi auto pistol rounds. For me I would take .357 SIG over 10mm or any other auto loading pistol round for a self defense.

    The 5.7 is a cool round but it has less recoil than a 9mm and is shaped more like a rifle cartridge. Pretty unique and would be hard to find anything to compare to it.

    In a pistol-to-pistol comparison, with 40-grain bullets, the 5.7x28mm EA loads achieve a muzzle velocity roughly 700 ft/s faster than the .22 Magnum.

    When 30-grain bullets are compared pistol-to-pistol, the 5.7x28mm EA loads achieve a muzzle velocity roughly 1000 ft/s faster than the .22 Magnum.

    Can't .357Sig also go through armor? Thought I read that somewhere a while back... :dunno:

    BTW, what does a rounds minimal recoil have to do with anything?

    Only way to make the 5.7 and .22 mag comparison is to take 5.7 fired from a handgun and .22 mag fired from a rifle.

    But I don't see what is so great about the 5.7. It is a very long round for a pistol and needs a large long grip. It's just to small and light of a bullet for me.(and I like 115 gr
    +p+ in the 9mm)

    How about a G35 with an aftermarket .357sig barrel?

    The 2.75-inch trigger-to-backstrap distance on the Five-seveN is shorter than that of a Gen. 3 Glock 17 (despite the 5.7x28mm cartridge's 1.6-inch length), and the grip widths of the two guns are identical, at 1.2 inches.

    Glock 20 with a 9x25 barrel seems like it would work for what you are talking about. Of course factory loaded ammunition becomes an issue.

    I was curious about that myself, so I decided to test it. I shot a 14 layer Kevlar panel with a 125 gr Speer GDHP from my P229 at about 7 yards. The bullet was stopped after about the 3rd layer. It did, however, have enough energy to blow the panel off of the water jug and land it back at my feet.

    This got me thinking about something...

    Panels are pretty cheap on ebay. I could probably buy an old/used one for around $20-$30. It'd be interesting to take a bunch of pistols to the range, set one of these up down range and blast away at it just to see if any rounds will actually penetrate and/or FUBAR the panel.

    ...ok ok... I really just want to see what happens when I fire my .460mag at it. I might put a something like gel or clay behind it to see trauma even if no penetration...

    ...but other rounds would be interesting to see first hand as well

    Actually, the kevlar panels I am using are roughly the profile and shape of a football. They have German wording on them, but I still don't know what they were for. A guy sells them at the local gun shows for $2 a panel. He said something about making knee and shin guards out of them but who knows. I just thought they were good for testing bullet penetration on soft body armor with.
