Because a lot of them look absurd and were only added to a gun with the SOLE intent of satisfying some anti gun state's regulatory bullshit, like CA or MA.
In other words, they were added as a feature to enable the manufacturer to sell the gun more than as something someone would actually use. Many LCIs remind me of things like that chunk of shit on my riding lawn mower that prevents me from
mowing in reverse- only added because some retard backed over his toddler with one and sued sears or something.
BTW, press checking is not that loud.

My glocks all have LCIs but out of habit I just pull the slide back slightly and see if the brass is in there. I don't really use the tactile LCI. This is force of habit. Once you develop it you will no longer care about an LCI. At all.
