I guess I am the only one out of step on the LDA, but, when handed one at the P-O booth at the IDPA Nationals, I COULD NOT MAKE THE BLAMED THING GO OFF.
It went like so:
Insert magazine, rack slide, aim, pull (light but gritty trigger with noticeable stack - I bet Todd J doesn't shoot that one), Bang.
Pull trigger again, nothing.
Rack slide, live round ejects.
Pull trigger, Bang.
Pull trigger again, nothing.
"You are not letting the trigger reset."
OK, I repeat the drill, being sure I get clear off the trigger after the shot breaks, Bang, pull trigger again, nothing.
I struggled and struggled with that thing, but could not reliably make it fire two shots in a row. Don't know what I was doing to it, I have no trouble with SA, real DA, or Glock.
Guy with me had no trouble making it work, but did not like the feel either.
