Most modern striker fired handguns such as Glock come with a trigger pull of around 5-6 lbs. And most single action guns such as 1911's have triggers in the same range unless they have been modified or left the factory as a dedicated target pistol. Most DA/SA triggers are 10-12 lbs in DA and the same 5-6 lbs in SA. The trend is moving away from heavy long DA pulls and toward striker fired, or SA pistols with 5-6 lb triggers in handguns.
Most defensive shotguns, rifles, and carbines are in the same 5-6 lb range. Most hunting rifles are in the 4-5 lb range when they leave the factroy, but many are adjusted to 3 lbs or less.
I don't know of anyone who feels those 5-6 lb triggers are too light for defensive work. I wouldn't want the same 3 lb trigger I use on my bolt action rifles on a gun meant for defensive use. But I sure wouldn't want a 10-12 lb trigger either.
