Para LDA info.....
Well, that's a lot of stuff about the LDA. Here's what I know about them so far.....The LDA is a DAO pistol that doesn't have 2nd strike capability. The hammer has a cam inside it that has the hammer strut attached. When you cycle the slide, it's the cam you are actually cocking.(Hence the part description...Cocking Cam) The hammer has a light weight spring that is responsible for "resetting" it to the "half cock" position. The light double action is primarily available due to the fact that initially, it's this light weight spring tension that has to be over come to bring the hammer back (as is normal with all DA pistols) to the ready to strike position. Once in the ready to strike position, the drawbar is resting against the sear, and the next trigger move will cause the sear to break clear of the cocking cam, and full mainspring (approx. 22lbs) force throws the hammer down. The hammer has a safety notch which disallows the sear to break clear of the cam unless the hammer is in the ready position. LDA's also have standard thumb safety, grip safety, and series 80 firing pin plunger safety.
As a note, Para sets their trigger pull on the LDA at 5 to 7 lbs. There are competent smiths out there who are already bringing that weight way down to suit the descerning pro's who need the ittie bittie weights.
The LDA isn't just a "safe looking on the hip" pistol, they're really fun to shoot, and every bit as accurate as the Para SA line. They take a little bit to get used to due to the different characteristics of the trigger pull, but nothing a hundred rounds downrange won't fix.
