Understanding our SF Holster numbering system.
Example:  SF100A, SF100 or SF100AS
"SF"	=	"Small Flashlight"
The 2-3 digit number (100)	=	The diameter (in 100ths) that the holster will accommodate (i.e. "100" fits 1 inch lights).
"A"	=	Indicates that the holster is designed to fit (SureFire) lights with an anti-roll (hexagonal) bezel.
If nothing follows	=	The holster  is roughly the same diameter from top to bottom (won't fit anti-roll bezels) but is ideal for use with "slimline" (non hex) bezel lights and for bezel-up carry.
"S"	=	Will be used to indicate that the holster is designed for "short body" lights (when we introduce them).
The following information has no relevance to holster fit, but is sometimes added to the SF Holster model number on packaging, invoice statements, and packing lists.
Example:  SF100A "LB"
"R" or "L"	=	Identifies a right or left hand holster:  R = right hand  L = left hand
"C" or "B"	=	Indicates color:  C = Concealco brown  B = Black
