Normally on a Enfield rifle that does not have wood crush or wood shrinkage on the fore stock trigger adjustments are made with the lobes on the trigger.
In the Canadian No.4 manual it states that the armourer when rifles are returned to home station the armourer "MAY" have to bend the trigger guard to adjust the trigger.
The "MAY" deals with wood crush and the angle of the trigger guard, if the fore stock has excessive wood crush there is no choice but to leave the bend in the trigger guard.
This is because there are no new fore stocks for replacement and the wood crush on the existing fore stock has lowered the front of the trigger guard.
This is why the Mk.2 Enfield's had the trigger hung from the reciever and the trigger pull thus not effected but wood fit of the fore stock.
The location of the trigger sear on the cocking piece bent controlled the length of pull.
Normally the first stage pull brought the sear to the bottom edge of the cocking piece, and the second stage would cause the sear to drop off the edge of the cocking piece.
And changing the angle of the cocking piece bent lowered the pull weight.
Bottom line you can make the Enfield trigger as slick as snot on a door knob by slightly bending the base of the trigger guard downward and lowering the position of the sear.
Then decrease the angle of the cocking piece bent to the desired pull weight. I have done this to all my shooter Enfields and it works.
I can also say after buying five triggers and trying to adjust the lobes on the trigger it is futile experiment when you have excessive wood crush.
Please download the No.4 manual I posed above and do some reading, the No.4 Enfield rifle is still used by the Canadian rangers and steps outside the original British manuals must be used because of no new parts being available.
