    Could someone explain to me the different types of pistol ammo? I've seen stuff like +p, -P, +p+ and the like. I've never been given a decent explination on what they mean or how they react in my pistol.

    Thanks

    +p, +p+ are hotter loads. Not all handguns are designed for them. I've never seen -P. Could be a target load???? If your not sure, use standard ammo. An extra 100 fps is not going to benefit you.

    Standard ammo (no "P") means that it's loaded to standard pressure hence standard velocity. Both +P and +P+ are loaded hotter to increase velocity and improve ballistic performance. Since it's loaded to higher pressure, it's important that your gun is built to withstand the extra stress. Somebody that reloads will be along shortly to get into all the stats & details...

    i agree with this.

    typically as you reach maximum loads you hit diminishing returns for the capabilities of a case, bullet and what your gun is capable of handling. most +P and +P+ loadings dont offer much if any real performance for the extra muzzle jump and recoil. you lose a lot of controllability for almost no gain.

    if you think your SD rounds need to be +P or +P+ you prolly really want a bigger gun anyway.

    +P and +P+ is a damn fine marketing tool and thats about it. it moves a lot more SD ammo when they stamp that on the box.

    There are really only 4 LEGIT +p loadings, as listed with SAAMI. Those are .38 Special, 9mm Parabellum, .45ACP, and ALL .38 Supers are +P. Simply a hotter loaded cartridge (but not all that much- a .39 Special +P is still way below a .357 Magnum) There is no OFFICIAL +P+, it is whatever a maker wants to call it.

    Me- if I want something hotter, then I buy a hotter caliber weapon. If you want a 45 Colt that shoots like a .44 Mag- BUY A 44 MAG!

    I was told a +p round is a hotter round used by police-If they needed to fire into a crowd on the street a +p will round will not pass through and hit multiple people,it would expand quickly,that is how it was explained to me.I had a AMT automag lll 30 cal. that would blow through five or six people so fast they would not even know,not good to carry on the street!

    someone been telling ya stories. not one bit of that is true. i can gaurantee soon as you pu that exact same round from the automag 3 into an m1 carbine going 600fps faster the same guy that told ya those stories will claim the 30 carbine isnt worth spit and bounces off enemy uniforms...

    A lot of police agencies issued +P+ ammo. Now they up the caliber and go +P. I shot a B.G. with a 110 gr 38spl +P+ in the chest and it opened to .61 and stopped just under the skin in his back.

    Well I was at a private shooting range with a 1/4 plate of steel hanging on a wire and from about 20 yards the AMT automag lll shot through the steel so fast I thought I was missing. I walked closer to see and it was passing through so fast it was not even swinging on the wire.Maybe at 200yds it would'nt have much left,but at close range it would pass through a house!

    30carbine in a pistol is a 110grn fmj going about ~1400fps in the carbine rifle its ~2000fps. hitting soft targets is different than shooting plates. you would be surprised just how difficult it is for bullets to pass through soft targets.

    the automag3 is about the same power level as a 9mm handgun. its a helluva fun round to shoot due to the enormous fireball and loud boom but its not a magic bullet nor is it a particularly weak one.
