just a bit of info I was asked why I prefer a 10mm vs a 460 rowland / glock conversion,
of course accurate and rapid and ,
at times repeated accurate shot placement
and a knowledge of your opponent's anatomy
is required in ANY defensive use!
it doesn,t matter what you carry,
if you can,t shoot it fast and accurately

you can upgrade a glock 45 acp to shoot the custom 460 Rowland cartridge
its certainly a step up in power to about 41 mag revolver power,
the 460 conversion offers certainly more than a 10mm,
but it's hard on the Glock converted,
and
you'll eventually have reliability issues in spite of what you read.
If you look hard you'll find examples,
but keep in mind many people who convert these guns don,t shoot them all that often
if you want more power in a defensive gun I don,t see the potential advantage,
as a 10mm with the correct ammo has repeatedly been demonstrated to kill even large bears,
and it will certainly shoot deep enough in a human opponent,
to prove lethal with good shot placement, certainly,
you don,t need more than the 10mm glock power level or more mag capacity
and you have a 15 shot mag capacity,
If I was hunting big bears a heavier hard cast bullet from a 7.5" or longer barrel revolver,
that packs considerably more power,
in a caliber like, 44 mag-480 ruger, 460 S&W or 500 S&W revolver makes more sense
human opponents won,t require nearly as much power to disable
460 Rowland is a lengthened, heavy duty . 45 Auto based
case designed by Johnny
Rowland.
It delivers . 44 Magnum ballistics in a semi-automatic handguns chambered for this cutting edge cartridge.
