    Actually I'm one of the few people on this forum that has been in a firefight before. Heck, if you go to the political section, most of the regular posters do not even own a gun.

    It doesn't matter if they are standin' or runnin' you need to spread your shots out for a more traumatic effect.

    P.S. I also see that with all your vast combat/SD/HD/LEO shooting experience you have obviously missed my joke.

    Did you know I have a JD from Harvard Law and a DD from Wheaton College.

    See how easy it is to do that on the interwebs ?

    Congrats! But it doesn't mean you know anything about guns, firefights, shootin' people etc.

    Man, don't you know I taught Sgt. Rock everything he knows?

  6. I believe I heard the FBI have switched back to 9mm.

  7. agree. Exactly what I carry and reload.

  8. FBI switched back to 9mm for two reasons: 9mm has less recoil and the ammo is now much improved thus permitting more accurate repeat shots with more deadly results. However, the .40 is still more effective even with increased recoil, if you diligently train with it and use superior ammo such as 180gr Speer Gold Dot.

    Can you source your claim please?

    I wouldn't use "superior" in conjunction with any service caliber handgun ammunition. As for why the FBI switched to 9mm, how about citing the FBI's justification, specifically:

    • Caliber debates have existed in law enforcement for decades
    • Most of what is “common knowledge” with ammunition and its effects on the human target are rooted in myth and folklore
    • Projectiles are what ultimately wound our adversaries and the projectile needs to be the basis for the discussion on what “caliber” is best
    • In all the major law enforcement calibers there exist projectiles which have a high likelihood of failing LEO’s in a shooting incident and there are projectiles which have a high ting incident likelihood of succeeding for LEO’s in a shooting incident
    • Handgun stopping power is simply a myth
    • The single most important factor in effectively wounding a human target is to have penetration to a scientifically valid depth (FBI uses 12” – 18”)
    • LEO’s miss between 70 – 80 percent of the shots fired during a shooting incident
    • Contemporary projectiles (since 2007) have dramatically increased the terminal effectiveness of many premium line law enforcement projectiles (emphasis on the 9mm Luger offerings)
    • 9mm Luger now offers projectiles which are, under identical testing conditions, I outperforming most of the premium line .40 S&W and .45 Auto projectiles tested by the FBI
    • 9mm Luger offers higher magazine capacities, less recoil, lower cost (both in ammunition and wear on the weapons) and higher functional reliability rates (in FBI weapons)
    • The majority of FBI shooters are both FASTER in shot strings fired and more ACCURATE with shooting a 9mm Luger vs shooting a .40 S&W (similar sized weapons)
    • There is little to no noticeable difference in the wound tracks between premium line law Auto enforcement projectiles from 9mm Luger through the .45 Auto
    • Given contemporary bullet construction, LEO's can field (with proper bullet selection) 9mm Lugers with all of the terminal performance potential of any other law enforcement pistol caliber with none of the disadvantages present with the "larger" calibers
    The FBI basically says that your "superior" statement is not only false, but a plain myth, not supported by real world data. .40 S&W is 1mm larger in diameter and 2mm larger in expanded diameter, if it expands. That's all.

    PS: I sometimes carry hot 10mm loads, so don't tell me about how "superior" your 10mm short and weak is.

  11. They are comparable. However, for CC, the small 9mm's are much easier to conceal. ie" Kahr PM9
