I filed mine down so it wouldn't stick up. It doesn't answer your question about a different barrel, sorry! However you can remove it so a standard barrel will fit, I just didn't want a hole in top of my slide.

You just take off the optic/ rear sight plate then it comes out easy. There is a spring and the lci lever itself.How hard is it to remove? I assume i have to take apart the slide, correct?
