You need a gunsmith to work that trigger and likely some would pass on the job. I did one and was fearful I would ruin the thing. The only way to fix one that's ruined is to buy the entire assembly at a substantial cost (last I knew at least). Luckily, mine turned out quite well. Sold my Omega rifles later as I just couldn't stand that trigger guard slamming heck out of my hand with every shot. Enlarging the trigger guard would mean enlarging the entire action and those that like it now would surely not like the change. Maybe TC could do a limited run of Big Boy Omegas.

I'm not sure I would ever attemptan Omega trigger jobagain and certainly not on someone else's rifle.
