Well...thats honestly like asking what combination of mouthwash,toothpaste and tooth brush is the best?!?!
There is no best holster, trust me...Ive been trying to make it for years.
Look at what you want it to do......is comfort or concealment or reholstering or stability or tuckable or spring clips/snap loops????????? Your number one requirement? what is your second? Third??????????
Analyze what you want it to do and look for the best you can find given the criteria you come up with........
If your still lost, call me and Ill help steer you the right way.
Shoot well and god bless
