+1The is no "best".
What holster is best for you depends on many factors, starting with how you plan on wearing it: Concealed strong side, cross draw, inside the waistband, shoulder holster, exposed as a hunting or field holster, a mass produced factory holster, a one-off custom made holster, an inexpensive holster or one made by a top of the line maker that costs some real money, etc . etc.
The best advice is to get online to the many holster makers web sites and see what's available that might fill your need.
Be aware that most gun owners tend to wind up with a box of holsters that just didn't work for them.
If you try one and it's not what you want, sell it and buy another.
