Sigma HSM 70-200mm and Teleconverters

Can this lens be used with Tamron 1.4x, Tamron 2x and Pentax AF 1.7x teleconverters? Any info is appreciated.

I have it, I tried it (with SDM contacts) it performs well but hunts a bit in lower lights conditions

Tamron-F AF tele converter 1.4X Pz-AF MC4

But with cleaning of the contacts performed better(Also using Focus lock helps,as well as MF in difficult cases)
