Went into my local shop looking for a CC pistol for around $400 walked out with a Sig P320 Subcompact. It just felt so damn good in my hands. I originally didn't plan to spend that much but who can put a price on your life or whatever i need to tell myself to justify it. Well I had done a ton on research on a bunch of other compact and subcompacts in my price range and none on the Sig. After the fact I found out about the RX. I am a techno junkie and wish I knew about it before making my purchase because I likely would have spent the extra to get the RX. Well now that I have it I wanted to weigh my options. Doing a little digging around it seems my options for having the Romeo attached is to go to a smith and have it milled and attached, buying a new RX, or going with another aftermarket reflex. Is this correct? I appreciate any input. Thanks everyone.
