Don't think its as simple as that. I have a Mk1 EV2 like Holly. I reckon the sears have probably worn, or something aint quite as good as it should be.
I have my trigger st up as good as its gonnae get. I have a first stage and a relativlly crisp 2nd (could be better - my comparison is tio my s400 trigger which was all polished and copper crimped washers etc, that snapped like glass). But to get that I had to increase the trigger weight. Bringing the weight down, would result in loss of 1st stage, but would say as a single stage it was crisper.
Having tried several other match rifles I do reckon the EV2 Mk1 (at its now age anyway) is way down the list of good triggers.
