The 9mm cartridge was never meant to be used in revolvers.
Revolver cartridges are crimped; Semi-auto pistol cartridges are not!!
Semi-auto pistol cartridges were designed to be use with magazines.
If you do use a semi-auto pistol cartridge in a revolver, the revolver should be
HEAVIER than the "LCR" is.
If the revolver is too light, it will recoil more; and, the semi-auto
pistol cartridges will hit the revolver's recoil shield with greater force.
Each time the revolver is fired, this greater impacting force against the recoil shield
can gradually dislodge each remaining bullet from its respective shell.
It is simpler to just trade-in this revolver, and purchase a 38 special
or 357 magnum.
Preferably, cartridges used in revolvers should always be crimped!
It was not a good idea for Ruger to market this type of gun.
The Smith and Wesson model 929, or similarly heavy handguns
are more practical implementation of the 9mm revolver.
The Smith and Wesson model 625, in 45 ACP, is another good
example of a heavy frame taming recoil and reducing the cartridge's
impact force against the recoil shield.
If Ruger designed a 9mm GP100, that would also be a practical
implementation of a 9mm revolver.
