Which XC1 do I have? Only one thing matters here: the XC1-A and XC1-B are the same size, so they take the same wrap. The XC1-C is a different size and has its own cut. XC1-A or XC1-B → choose either XC1-A or XC1-B above. Identical panel. XC1-C → choose XC1-C. Do not order the A/B cut for a C, it will not line up. Telling A from B (it does not change the wrap, but if you are curious): the A is 200 lumens with a separate cross-bolt slider for constant-on and a flush battery cap. The B is 300 lumens, activates constant-on with a quick tap of either switch, and has a longer reinforced battery cap. Both run a single AAA. Telling the C apart is easier — it is visibly a different body. If your light does not match the A/B profile, you have the C. Not sure?

The XC1 is a small, smooth aluminium body that lives in a holster and against a beltline, which is exactly the combination that wears finish off and makes a light slick to index under pressure. This adds a sacrificial layer and real texture, without adding enough thickness to change how the gun holsters. Cordura® 1000D, MIL-DTL-32439 compliant. IR compliant and Berry compliant. 3M Low Surface Energy adhesive. Grips mechanically rather than bonding chemically, so it comes off clean. The lens, switches and mounting hardware stay completely clear. Nothing about how the light works changes. About half a millimetre of added thickness. Most kydex absorbs it. Installs in minutes. No tools. A 20-minute window to lift and reposition before the adhesive sets. Cut and made in Pennsylvania. Wrap only — the light is not included.
