Any straight-drop holster that is not off-set outward from the belt, and which holds the gun so that the frame front-strap is above the belt, is going to be suitable.
I have about ten "suitable" holsters, and don't see much of a performance difference among them.
I bought an Uncle Mike's holster, for about $20, for one-time use of a borrowed gun. No issues with it, at all.
I'm currently using a hand-made, $100+ leather holster, and no issues with that, either.
