I used to blow these off as incredible dumb
BUT...
Actually - these have a very useful application -- I would recommend a trigger guard cover though -- a buddy of mine runs one on his G19 - and uses a cut down Raven VG2 piece on a tether - so when he draws the trigger cap "cap" pops off.
This application works very well in the low-vis/covert world where you can't have a holster - and a string around your waist under a man dress is all you have. I've seen them run as well appendix for LE Drug/UC Work (with same trigger cap) - and while not a holster - they do offer some advantages in those applications.
