45 to 9mm.......

[fastarget]

Is there a barrel and bushing, that will convert my springfield 45 to a 9.
Or do I have to go with a new slide, firing pin, barrel etc.
thanks for any info

It's not that easy, you will need a whole new top end (slide, barrel, extractor, firing pin etc) plus a special ejector (Wilson Combat has them, which is usable with both .45 ACP and 9mm).
