This would be a good one for you to peruse and chew on, Rich.
Not that you can't, but you don't have to shoot all guns the same way. Although in both instances you pull the trigger and the bullet comes out of the barrel, the internal and external mechanics are different between your Glocks and LCR. IIRC, DB states in that thread that he had an epiphany when an instructor told him, "That Glock isn't a 1911..quit trying to shoot it like one.", or words to that effect.
