I see a lot of people replacing their stock triggers with an Apex. I'm not a big fan of altering guns and putting stuff that's not from the manufacturer on them as I'm afraid they will fail, nevertheless, I am wondering what exactly is wrong with the stock trigger on these guns? Is it too heavy? Too light? What?

I personally do not like a "light, sensitive" trigger because that can be a problem. I like my trigger to be not too heavy, not too light and I think the trigger on the M&P 45 is just fine. I haven't tried an Apex so I don't know what the difference is but if you guys can please explain the differences and why you prefer the Apex over the stock that would be awesome so I can understand a bit more. Thanks.
