I just bought the gun last night and after taking it home and assembling it and doing some dry-fire practice it's clear that the trigger is.....not what I was expecting.

I've never dealt with shotguns before and my Weatherby Vanguard is my standard for comparison, but do shotguns normally have so much creep and such a weird "flappy" break at the end? I'm used to the trigger on my rifle suddenly and crisply breaking under the application of pressure, not this thing where I pull the trigger farther and farther back until it sort of cruches into position. Is this normal, and if not, what should I do about it?
