Didn't someone on this board mention that there had been an inordinate number of problems with the LCR in 9mm???? IIRC, a significant number of manufacturers don't crimp the bullets enough and the high velocity combined with the light weight of the pistol was allowing bullet-creap and locking up the cylinder. There's no "immediate action" drill to fix that in a gunfight.
Sure there is....pull out your other gun.
A lot of guys I know in the Soldiering /LEO/ Gunfight business have a BUG no matter what they're carrying as a primary, even if they are on a grocery run.
