 GUNSMITH NEEDED! Problem with LDA safety!

here is the problem with my LDA... please tell me if you know what's causing it.

when you try to engage the thumb safety, it will not fully engage, the only way to fully engage it is to manually push the hammer (this is the gun with the flat shaved off looking hammer). Additionally, once the safely is engaged, if you take it off, the hammer partially moves back to the cocked position...

I do not know what is causing this, and i am worried that it will make the gun unreliable.

additionally, should the hammer remain cocked when the mag is loaded and the slide is racked? The hammer does not fall back like (i think) it used to, but it can be manually pushed all the way forward... is something broken in my LDA?

gun fires and feeds perfectly as always, but the trigger seems a bit different... (could be completely my imagination as i am a bit nervous with the safety acting up)

When your LDA is (pre) cocked and ready for use, the outside hammer should be slightly raised from the position it sits in after you pull the trigger on an empty chamber.

The behaviour of your safety is not correct. Para's wty is lifetime to the original owner. Did you buy it new?

Interesting, but not helpful, that your LDA trigger is acting like C&S's SFS system for the Hi Pwr. I'd call or email Para.

fixed it... completely disassembled EVERYTHING, and put it back together... there was a spring that had come off and was not resetting the hammer after cocking.. it works as it should now.

YOU are amazing. I get frightened every time I FIELD STRIP mine. That lock system is pure voodoo.

to be completely honest with you, i was in absolute terror when i took that thing apart... it has more parts than my ar15.... but i was VERY careful to note the position of EVERYTHING before i pulled any pins... it took me 2 hours of HARD work to get it together last night... since then i have taken it apart 4 times just to get the hang of it... i am now very comfortable with the reassembly, and it no longer seems like an impossible puzzle...

just fyi... you really DO need to know how to remove the thumb and grip safeties.... if you take them off you can lube the internal hammer mechanism without any risk of damaging anything or having pieces drop loose... but one word of advice... on the right hand side of the grip safety, there is a small flat piece that you can easily miss when you take off the safeties... it is held in by the same pin that holds both safeties in, and once you remove them, be very careful to keep the gun flat with that side down so that the piece doesn't fall out before you see how it goes in... if you do that, you will be able to put lube in the internal mechanism... this made my trigger MUCH better.

once i had figured out how to take it apart, and how it all worked, i decided to do some customizing... i pulled out the grip safety mechanism, and polished the part that stops the hammer from moving backward until it is depressed. I took roughly 1/8th of an inch off, then reassembled the gun. The trigger was noticeably smoother. I went and fired it today, and it is every bit as dependable as before, and MUCH more smooth... (300 rounds ZERO issues)

i have since torn it down 9 times and reassembled it. I can now put it back together in under 20 minutes. This gun is incredibly complex, but it is not impossible to figure out.
