m&p 1.0 striker block general timing question

[Bobafett]

I have 2 m&p 9 1.0 s one 9c and one CORE. both have standard triggers

just curious, I have not experienced any light strikes but notice that one pistol the striker block is fully depressed before the sear is engaged and the other is only partially depressed, it becomes fully depressed as the sear moves downward.

TIA
