1813L Trigger

[XM21]

I have an Anschutz 1813L that needs a trigger.

I have a lead on a 5020L but the factory called out a 5018L
a quick look online shows the difference to be the weight 90-650g instead of 60-490.
Is that the only difference and if so, does it really matter? Seems pretty small.

That's about a 1 0unce difference at the lowest setting. I doubt most people can tell the difference.
