    This is my simplistic thought on 9 vs. 40 ballistics: I have extensively shot the Ranger T series (Winchester's numbers below) and have found that when comparing 9mm and .40 I personally deal with the recoil of the 9 better than that of the .40, consistently putting 3 rounds of 9mm on target while only being able to put 2 rounds of .40 out in the same time. So for me it is simple math.

    3x 441 ft-lbs= 1323 ft-lbs on target
    2x 476 ft-lbs= 952 ft-lbs on target

    Blackdog said it up there somewhere........ shoot the biggest bullet in the biggest gun THAT YOU CAN AFFORD TO TRAIN WITH!!!!!!!

    My opinion only...... your mileage may vary

    Let me put some perspective to what is becoming a ""stopping power"" discussion: In the early 70's, there was a shooting in either LA or NYC (I can't recall, I have slept since then). The suspect was shot several times with revolvers, and two 12 gauge slugs, and still ran another block before having the decency to die.

    The only round I know of that stops them for sure is a 155 Cannon round, direct hit. I did see a video of an Iraqi who shot at a U.S. Marine helo. The helo was out of 7.62, it was out of 40MM, but they did have a TOW (anti-tank) missile left. The TOW actually impacted on his AK47. That was also a positive, if expensive, kill.

    So, never expect your round of choice to work. Anyone worth shooting is worth shooting to the ground - 9mm, .40, .45 matter not. Surviving matters - in fact, survival is the ONLY victory.

    the reason i got the PM9 and not the PM40 was when i bought the PM9 i wasnt a sworn LEO yet and didnt have a .40 duty weapon. i didnt see a point in selling the 9 to get the .40 version in the kahr. im very happy with the 9mm little kahr. if i had bought it after getting my G23, then i would have gone .40

    I carry all 9mm's - on duty, off duty, BUG, carbine. I'm comfortable and confident with the weapons and the load and shoot very well with all of them. If it's too much for them I've got the 5.56 and 12ga backing them up.

    It really doesn't matter if you ask me. It is all about hitting your target and the way the target will react. There are plenty of videos on-line that you can research and see people shot with .45s and they still keep going. In the town I grew up in, some kids were fooling around with a .22LR in a pistol or rifle I don't know. Anyways, the driver side backseat passenger pulled the trigger on accident and the gun fired. The bullet went through the seat, into the back torso area of the driver. The driver died from being shot once with a .22LR. Another recent robbery of a pawn shop: Guy walks in with gun. Pawn shop sells guns _and_ keeps them loaded and ready to go. They can pick-up any gun on display and start firing. Anyways, owner sees the robber, pulls his own .32 or .380 (don't remember) and shoots the robber, hitting him at least once. The robber turns around to flee and another clerk grabs a .44mag. Shoots the robber through the back. The bullet goes through the robber, through the front glass door, and hits a car across the street and drops (the photos showed it didn't penetrate the quarter panel). As soon as the bullet hit the guy, they reported he dropped to his knees, then fell over and died. Not sure if it was a .44mag or .44spl, hollow point or what.

    "Supposedly a robbery, but nobody saw nothing..."


    So, so true. It seems like I've heard that somewhere.

    From what I'm finding, the 9mm is still more than adequate as a duty round, however it seems that hardly anyone (especially in my area) carries 9mm any longer.

    Discuss.


    Oh, God. Not again.

    Shot placement. It's better than bullet diameter.

    45acp > 9mm > 40S&W in that order.

    I've never been able to understand the, "more concealable argument" when discussing 9mm vs .40 S&W. Virtually every 9mm model pistol I'm familiar with has a .40 S&W "twin" made by the same company and the larger caliber weapon's total capacity differs by only one round. I suppose it's possible that the additional round in a 9mm pistol could make "the difference" in a lethal force incident, but so could hitting the suspect with a larger diameter, heavier bullet. Personally, I'd feel better using the bigger bullets, but having a total capacity of one less shot.

    With that being said if my clothing allows for it i will carry the larger .40 but thats only during the winter really. i also carry an extra mag religiously when i carry the PM9 as its only single stack and im more comfortable knowing i have the extra 7 rounds in the pocket on top of the 7 in the weapon.

    seems most of the departments in our area carry the 40, SW Ohio. I carry a 40 or 9 off duty. I personally like the 9, since the gun usually carries more rounds than a 40, I dont need two magazines. I dont usually shoot at cars off duty unless they cut me off haha. I carry the nine more out of convenience than anything else. However, with the glock compact 40 and 9 they are both similar in size so I have to agree ford/chevy debate, course I prefer Nissan.

    OK, Sleuth will convene the ballistics class once again:

    Internal Ballistics: Who Cares

    External Ballistics: See Above

    Terminal Ballistics: Shot placement, shot placement, shot placement

    The reason we don't carry .22 shorts? Because we cannot guarantee our ability to shoot the outlaw in the eye from any distance while we are both moving. With ammo designed since the FBI Miami Shootout, the caliber makes little difference.

    Me, I carry a .45 or a 9mm - I never got into the .40, but if it floats your particular boat ...

    As a civilian I don't picture too many scenarios where I'd have to worry about windshields, but I would be interested to hear your thoughts on the matter.

    Due to an old wrist injury I prefer 9 or 45 to 40. There are settings where I like the option of having more rounds available (9mm), but my usual pick is the 45. My carry choice in 9mm is Ranger 115g +p or Buffalo Bore 115 +p+. For greater penetration, I'm impressed with the semi-wadcutter 147g. In 45 I carry rounds with the 185g Barnes XPB copper load.
