I had that happen with a new Springfield once. It blew apart on the first magazine.
My gunsmith at the time told me that bushing failures are not uncommon.
I guess it doesn't hurt to keep a spare in your shooting bag.
Finally received a new bushing today. Unfortunately, its OD is smaller than my old bushing was, so when I install it - it's so loose it rattles. :mummy: I don't have a micrometer to measure the exact difference, but just using my dial calipers it appears to be about 1/128" smaller. Another email is off to DW asking for another bushing... I'll post another update when I hear back from them.
Probably had some stress left from heat treating. Not unusual with parts with that shape and made in high volume. I would suggest mailing it to DW so they can send one the same OD and ID. Current address is:
CZ-USA / DW
5169 State Hwy 12 South
Norwich, NY 13815
Thanks Dean. I spoke with DW CS about it and was told that the bushing I was sent was the only size available, and that (I quote) "the tightness of the bushing has less effect on accuracy than everyone thinks". I'll just buy a new bushing myself and have it fitted the right way...
