No "Bacon"?
I guess the people who carry concealed bacon have to pick "other".
No particular order, but what I have seen here on INGO:
Glock 26/27
LCP/Keltec
Smith Airweight
Glock 19/23
Smith M&P Compact
Ruger SR9C
Those are the most talked about ones I have seen on INGO (and other places online as well)
