Can a "spurred" hammer from a USP be put into a USPc?

[G20-IWB24/7]

To all of you HK armorers out there---can the spurred hammer from an full-size USP be "dropped-in" to a compact, so I'll have a spurred hammer???

Yes... A buddy I went to school with had a spurred hammer put on his uspc 9mm. I think he actually sent it to HK to have it done.

Yes, but you have to make sure to get the right hammer, since there are at least two kinds!

You can either put the full size's hammer on the compact or the compact's hammer on the full size, can't remember which way it goes.
