Alien Resurrection begs to differ. Spoilers.

the bit when they climb out the water up the ladder. One well placed bullet to the head killed one from a pistol killed one.

That's my point though. It's either a retcon or the shot went through because it was super high powered. Aliens made it clear that handguns do not affect Xenos even if they only a mere few feet away. Gorman shoots one in the face multiple times and the bullets bounce right off. Vasquez could only kill one after shooting the same spot at point-blank range like 3-4x before a shot gets through and it bleeds.

This is 100% wrong. The entire reason the acid for blood was put into the movie was to prevent just use a gun. Aliens shows they are susceptible to conventional weaponry.
The Marines were absolutely not using conventional weaponry, though.

Also Hicks using the shotgun
Well it IS a shotgun. Probably slug too. That's just my guess though.
