SO Here ya go with info and pics on these two blocks
There is the standard block and the Low Profile block
I am 100% SOLD on the standard block
As you can see int he pictures below the Low Profile block actually moves and when unloaded there is a large gap in the top of the slide where it dips down ... but when loaded it does pop up nice and straight and is very minimal with a slight tactile feel.
BUT the picture below it is the basic standard block and it sits perfectly flush with the slide .... and the best thing .... IT DOESN'T MOVE!!!
So when loaded or unloaded the LCI stays put and is really just a black block so that the pop up LCI is now gone and there is no white lettering or red pop-up
Plus as you can see there is still a slight gap on the top part of the barrel and slide where the LCI does not go all the way .... this is so it does not pop up but still has a loaded chamber indicator Hole like the regular M&P's have so even though there is no block popping up anymore telling you it's loaded there is still a hole so you can visually inspect. Basically the tab does not stick down over the breech face to interact with a chambered round.
I do not like the low profile block really ... the regular block is PERFECT, cover the slot with no white lettering anymore and doesn't pop up anymore but still gives you a loaded chamber hole indicator!!!
Hope this helped ... here is the pictures and links to the product.

Nice option if you still want the tactile loaded chamber feel on the block ... not a fan of how it looks when unloaded. But still a great option none the less.

Best option in my opinion ... does not move or pop-up at all but still has loaded chamber hole for inspection! (I will be buying this one)
