Well not sure which trigger it is, and really doesn't matter a lot as tyye are all the same except for looks.
as mentioned by Dbeardslee, you can lock the pistol down by adjusting it incorrectly.
BUT, to adjust the trigger , cock the hammer (of course all this is done unloaded.), and tighten the set screw down until it just will not fire when the trigger is pulled and all the safeties are off (thumb and grip), then reverse the set screw about 3/4-1 turn and its adjusted.
Personally I have adjusted every 1911 trigger i got except on the New PT1911AL, it ws simply perfect from the box.
Now what the trigger adjustment will do is vastly improve the trigger reset for fast accurate followup shots. Most of mine are about a 1/8-1/4 inch reset.
Now of course if it is working fine and meets your taste in trigger reset and over travel, just leave it along.
hope this answers your questions.
