My preference on a CCW is to use a shorter light for comfort. The TLR 7 series fits that purpose especially for AIWB. I have the A, X, and now the HL-X. I like that the HL-X has 1000 lumens versus the other two having only 500 lumens. The battery that comes with the HL-X is rechargable and I'll need to see how well it holds up over time.
