Not really, it doesn't have a firing pin block like every other striker fired handgun, it has a weird sear block thing from a hammer fired handgun because it's a shitty hack job conversion from the P250
None of this is a sear block, or has anything to do directly with the sear. It will prevent the gun from firing if the sear were to fail.
