update...
the fedex guy dropped off my wilson slide lock extended lever.
i used only 1 pair of "special pliers" that i bought from the HK Gun website, that aids in trigger spring replacement, that i used months ago, on my 2 Beretta's
the whole switch out took me..........
"about 10 minutes"..........ok
@Belt Fed , this time, you were right...!!!!!!
before with the OEM slide lock
after with the Wilson extended piece
the "special trigger spring tool" from HK
and with the jaws open
in one video, a guy said you have to remove the trigger.......BS
in another video, another guy says to use a "pick" to pull up on the trigger pin, but this did not work for me, so i got out that special plier, and it was a piece of cake..!!
