Hello. Im in the process of gathering parts for a 6" sti build on a standard length frame in 9mm for multigun.  I have never handled a 6" pistol.  I seen a picture you posted a few years back of the "glimmer twins" one a fluted bull barrel and the other a bushing. Would like to know what you thought of each and how they handled compared to an Edge or similar. Any help is appreciated.

Thanks, Jess
