marlin x7 trigger

i just got a new marlin X7VH rifle. It has the pro-trigger, or the savage accu-trigger look-alike. Anyway, although the trigger is adjustable for poundage, the trigger has alot of creep and is gritty when squeezing. I'm wondering if anybody knows whether there is a replacement trigger for this rifle, either from rifle basix or timney. I think I will like the rifle when I get the trigger cleaned up. It was kind of windy today when I first shot it, but after shooting 20 rounds through it, my last 3 shot group was measured at 13/16" of an inch. That's with using plain jane hornady factory ammo with 55 grain sp, so we'll see what happens with it. Thank You
