Cocking piece difference in No1 and No4 etc

I don't understand, all you have to do is press the trigger and flip the bolt handle down if you don't want to dry fire it...

Just for safety, when you raise the bolt handle to decock and the assembly moves rearward, check under the extractor for brass before pulling the trigger and lowering the bolt handle. It doesn't take any more time, and you don't get a surprise the next time you check the weapon...
