Which has greater muzzle flash? 9mm vs .40 vs .45

On a more serious note, My ruger sp-101 with a 3 inch barrel shooting 125 gr 357 hollowpoints lights up the the entire northwestern hemisphere -while my glock 9mm shooting a similar bullet weight at almost the same velocity doesn't- a lot has to do with barrel length and powder charge(type of powder- slow or fast burning -tho these are relative terms...)All pistols will have some flash as the unburnt powder continues to burn as it leaves the barrel - shorter barrels yield more unburnt powder and more flash - I think this has less to do with the diameter of the bullet and more to do with the length of the barrel. There are many "low flash/low recoil defense rounds out there -see which works most reliably in YOUR gun...

lol I've shot the S&W 500 there, it's pretty rad. Unfortunately for 7 dollars a round I guess it'll be my only time shooting that gun.

its $5 a shot now, regardless if you use the reduced recoil, normal load, or hot load. still, theres no way id pay that to pop off one shot of the 500.
