Gen 6 fit guide
Where 15 holster makers stand on the Gen 6, and where each position comes from.
TLR-1 family
TLR-1, HL, HP and HL-X, version by version. The HL-X is the one makers single out.
TLR-7 family
TLR-7, 7A, 7X and HL-X, version by version. A 7A holster doesn't always take the HL-X.
X300
X300U-A, X300U-B, and the makers that don't say which mount.
