Probably a better feeling trigger than the G2S since it's a pound lighter.
That said I still switched from RR to the G2S's.
I can't say anything about the RRA triggers as I don't have any, but I have G2S, SSA, & SSA-E's & both the G2S & the SSA with a Wolf reduced trigger spring come in at a total pull weight of 3.5 lb, which is exactly what the SSA-E comes in at as purchased.
And I can really tell very, very little difference between the 3, with the G2S & the SSA set up that way.
Given that the every G2S is not tested or certified, I suppose it's possible that given enough of them, there might be some level of difference in them, but it's a very good trigger & will make most very happy in anything but perhaps the most precise of the precise rifles.
To me, none of the Geiselle 2 stage triggers are quite as glass-rod crisp as a good single stage or a bolt gun trigger, but they are very, very good, & safe & easy to use.
JMHO, JME
