Good to know. I may just give the new owner the replacement and have them deal with it. Thanks for nothing Springfield!

I have an XD .40 that has a stubborn rear sight. I'm trying to replace the factory rear and can't get the old one off. I've tried a sight pusher, brass punches with full size hammer and it won't budge. I've read that using an air chisel works but the gun is already sold so I don't want to damage it. Any ideas or tricks? Would heating it up help?
