It depends....some trigger pulls are still pretty light despite being striker fired and plenty of people have been "Glock legged" There are several striker fired pistols available with an additional safety.My understanding is that with a striker fired pistol the safety is in the trigger so a separate manual safety is not necessarily needed
No and No.Are ALL striker fired pistols like this or are the S&W guns the only ones so far that have the trigger safety?
Glock, Springfield, Smith M&P, Ruger SR9/40 etc. all have trigger safeties.
Kind of...Also, does this mean that the gun has to be a double action only?
Glocks and some others use a partially cocked firing mechanism where pulling the trigger finishes cocking the striker and releases it. Other guns such as the Springfield XD/XDM have a fully cocked striker where pulling the trigger ONLY releases the striker.
The partially cocked guns are considered double action only (it's topic of great debate every now and then), while the fully cocked strikers are single action only.
Clear as mud, right?
