I traded off my G2 because of the trigger. The G2 trigger is sufficient for 98% of the shooters out there, but I'm not one of them. If you plan on shooting IHMSA or doing precision shooting, the G2 trigger may not make the cut. My 2 easy open frames triggers are 6 and 8 oz.s, and there are times they feel like I am pulling a truck with my trigger finger. For hunting, I change back to a stronger trigger spring and give the sear engagement another 1/2 turn, and viola! I've got an unbearably heavy trigger again! It takes roughly 5 minutes to do so. The design of the original Contender is very user friendly.
Since you plan on hunting with it, I'd say the G2 would be the better choice. The factory trigger should suit you fine, the re-cocking feature is great for hunting, and I understand the G2 is a little stronger frame. Whichever you choose, Enjoy!!
