Had a number of longer discussion with Paul Sharp 'bout this regarding decocking a 92 in usage. We differed in what we said/understood, but I think that is because my background is with USPSA.
In gun games, the stages are so short that the "engagement" tends to roll right along the end of the stage. If you're doing it right, there is hardly a moment where you're off the trigger.
It is interesting that in some more of the defensive shooting classes I've taken, I tend to decock not even knowing it... E.g. when he gun comes back to "ready", it just sorta ends up decocked.
MikeC mentioned that this is a discussion worth having. I agree...
