HK45C and USP45C parts interchangeability

I know magazines will run between the guns.

Will the LEM trigger from the USP compact work in the newer HK45C? I’m going to guess not since the LEM triggers for the 45C took a while to come in.

Will the barrels interchange between the two guns?

Thanks

Since you aren’t getting an answer here you might want to check on the HK forum.

Try to contact directly to HK as well.

HK Customer Service replied in their forum a while back that the HK45c and USPc kits are different.

The barrels will not interchange between guns as they are slightly different.
