As I said above:
"The LC9 only releases the trigger block when the slide is racked. Cocking action is done by the trigger."
If the trigger block isn't released, no second strike.
But the trigger still performs
TWO (double) functions.
Even my SR9 performs
TWO (double) functions. The slide cocks the Striker 75%, but
ONE OF the trigger functions is to cock it the other 25%.
Even though I think of it as 1.25 Action, Ruger says it's Double Action.
But at any rate, the LC9 is
DEFINITELY Double Action. The looong pull to cock the hammer is the biggest complaint people have.
If I haven't convinced you by now, I'll not continue trying. I think it's a matter of context as to the meaning of "double" anyway.
The LC9 is not carried "Cocked and Locked", the 1911 is. (at least by most folks)
