RC4 Kydex sheat adjustment?

[Spectre6]

Ive got an RC4 that I love and use constantly when my unit goes out to the field. The Kydex sheath it came with is a little loose, even with the screw up higher.. Is there any way to improve the retention of the sheath?

Not out of experience but i've read that you can warm the kydex to make it flexible and bent it inwards to your liking.

Reef the top screw a little more. I found playing with it, even 1/4 turn had quite an effect on the ease at which the knife would go in/come out of the sheath.
