I'm getting ready to add a barrel/caliber to my two 1911 conversion setups. I have 2 45acp 1911s that I can change calibers on by changing the slides.
One 1911 goes from 45acp to 9mm & 38 Super, the other goes from 45acp to 9mm, 38 Super, and 10mm.
New 9mm barrels showed up yesterday, so now I can start converting them to 9x23. This should be an interesting conversion.
