So, to be truly deep carry, you'd need to put the Convoy clip on the last notch of the UT20 tail cap. I had the clip sent via UltraExpress! I don't think you bought one (?) but the Nitenumen C8 OEM clip is very similar but has a more stable tube clasp. Plus a smooth nub on the inside of the pocket clip that doesn't tear my pocket but keeps the light put. I just transferred it to my TK15, the light that I've been using lately in & around the house (my UT20 belongs to my ready bag).
