I'll agree with Malpaso on this one. Depending on what I'm wearing, if I go to pocket carry, I use an Uncle Mikes' IWB holster. I leave the clip on mine, because I stick it in my left front pocket. Works great with my J-frame, should work even better with a tomcat. Yep, its the cheap way to go, but I'd try pocket carry this way, and see if it works for you, then consider a more expensive holster. It also is a decent IWB holter, although I don't know how well it would stabilize the short front end of a tomcat.
And kpel308 has some great advice:
... something that works for someone else may not work for you.
Good luck!
