    that CD looks like one hot load!

    Hey, I was not downing the DPX in any way. Again, the ONLY comparison I made in my original post was that they are both (usually) light-for-caliber. That's it. I made no statement whatsoever about saying that the projectiles themselves are in any way comparable in how they penetrate or how they expand.

    That said, I will not carry Critical Defense because I like heavier calibers. I also like to have more rather than less penetration. As for DPX, it certainly has a great track record. But it seems most of their offerings are +P. I don't really like firing +P in my 1911's. In 9mm I carry 147gr. WWB JHPs. They're really impressive (even for "cheap" bulk ammo). In .38 Special, it's either Speer Gold Got 135gr.+P Short Barrel or the standby 158gr. LSWCHP.

    As for DPX, I would carry it in my LCP if it came in a heavier weight. I'm sticking with FMJ's in .380 for now. Gold Dots seem to be highly rated. So does DPX and expansion seems very impressive. I'm still not convinced that in that little-bitty mousegun caliber that it will penetrate enough. I'd love for some more "real world" results to roll in.

    I would carry

    and CD is an XTP style bullet meaning more pen., less ex....



    the copper bullets recoil less to me than lead and are some of the softest shooting stuff i shoot...



    as for .380 DPX and GD's seem to be leaders. i was shooting some GD today and DPX .380. man are the GD hot.

    i would take the corbon DPX over the hornady critical defense every time. i'm not impressed with the inconsistent performance of gimmicky jhp's with jell in the tip...

    Yep the felt recoil is and will be softer because that is a function of projectile mass and velocity, all other things being equal.

    9MM DPX shoots like 38 Super to my hand in my full steel 5" 1911, and the 45 ACP version is soft as well.
    Extremely accurate and flat shooting though at distance.

    Emrah I personally don't sweat it being +P rated in velocity because it's not a training round.
    As beyond my initial evaluation and function testing (8 boxes of 20 rds) I don't fire it at all.
    The carry mags loaded with it are dedicated to carry only and then I keep two boxes in each caliber as reserve in my safe.
    Odds of ever needing to use it are low and if I did happen to pull the short straw then well the gun is built to take +P+ ammo and not suffer damage.
    Do not though shoot this stuff in a gun with an old & weak recoil spring, although that is a no brainer as nobody should be running an old & weak recoil spring anyway. :p

    Janq: Great explanation. I had never realized that DPX used all-copper. it does make sense that it will penetrate deeper with a lighter weight. I thought at first the lead-free was some sort of environmental gimmick.

    I found some info on the 9mm DPX round at another site: Corbon 9mm 115 where they do testing with a Browning Hi Power and Glock 26. Seems to be quite accurate and relatively low recoil. I'll be trying some out this year.

    Jang,

    Agreed. I'm not recoil sensitive. It's that I've found some +P's in my 1911's don't extract 100% of the time. I'm thinking the pressure rise is just high(er) enough from standard pressure that the case is still "swelled" and tight in the chamber while the slide is trying to reciprocate backwards. I've had my extractor claw skip over the rim, go backwards, and then try to load another round in behind the case still in the barrel (double feed).

    Now, in retrospect, this has only happened with my Springfield Ultra Compact (3.5" and not my Taurus PT-1911 or S&W 1911 ES. I tweaked the extractor tension on the Springer, but in all honesty, I really don't see the point of a +P in .45 with 230gr. projectiles that use their big beautiful weight to penetrate.

    Back to the DPX... Do any police agencies use it? Obviously the rounds like the Winchester Ranger, Federal Hydra Shok, etc. have a proven track record, but they have been out much, much longer. The DPX is a relative baby comparatively. I'd like to read up more on first hand "street" performance. Any links?

    LE agency ammo selection has a lot of factors to be considered.

    Reliability - It has to cycle in the duty guns 100%.

    Accuracy - It has to be reasonably accurate with cops who practice 50 rounds during qualifying once a year.

    Use - Are they looking for barricade-piercing, low penetration, what?

    Public Acceptance - Some of you are old enough to remember when Black Talon hit the market. "Cop-killer". "Ammo designed to shred internal organs". "Shoots with murderous intent". "Kills instantly". And others.

    Price - Some ammo manufacturers will offer discounts just so they can add _______ Agency uses our ammo. Whether the department furnishes the ammo or the cop has to buy it, it's a considerable monetary outlay.

    DPX IS the "baby", but it has some serious cutting edge technology concepts in the design.

    Do cops need a round that will penetrate 16"? Not unless they learn to shoot better, according to some of the reports I've been reading.

    Additional to the above there is the not insignificant factor of cost as related to agency procurement.....Which is my industry by profession.

    DPX is and has always been much more expensive per round than anything else on the commercial market of duty ammo.
    That alone is a very significant issue for agency purchasing agents as most right now are cash strapped, state and local.

    Here is an old article reviewing the product though as via LEO.com;
    High Velocity, Deep Penetration - Check out Corbon's DPX ammo

    As well like any other product in most any market rather than wonder and/or not know it is also very much possible to simply shoot the mfr. (Corbon not Dakota the commercial distributor) an e-mail inquiring about the product including any LEO agencies that they have listed as end users.

    I have no doubt some have adopted it as pretty much everything in market has been acquired by someone for some purpose; Local, state and/or federal...Which again is my industry.

    Emrah,

    Your personal and direct experience is an _excellent_ example of why in general regardless of ammo choice people should buy quantity of what they are thinking to entertain and to run it through their gun hard to verify function, as well as accuracy.
    Your specific gun model or even singular unit just might not like this specific ammo...Or even a specific lot of ammo as produced (!). It happens.
    Also different lots can shoot to different POI too.
    Defense/duty as well as hunters know to buy within production lot numbers for reason of accuracy alone.

    A good lesson to learn, know and share (!).

    I don't know how I missed Jang's post, but I agree it should be a sticky! VERY well written. Thanks Jang!

    I made the switch to Corbon DPX in .45 ACP about a month ago - and I've not looked back. I shoot it well, it feeds perfectly, it looks like one great self-defense bullet, so I am done. I will stick with the Corbon DPX !!!
