Re: 220 Combat TB holster
I have a SIG like yours , and a 226 set up the same way . I don't carry them , but some leather holsters are open on the bottom , to allow trash to fall out . I have found that this is usually adequate for the threaded-barrel ... You could shop for holsters with this feature , modify one , or have one custom-made . The light-rail and raised-sights are probably going to be more of an issue - the sights can snag and ruin your draw ... For custom-holsters , check Alessi , Ken Null , Kramer , and there are some others just as good ... Did you want to carry with the can installed ? (At the range , of course ...)
