I have made the comment that the Oklahoma Territorial Marshals have the most handicap friendly range I have ever shot at and now I will add that they have the easiest online registration I have ever used. So excited to be entered.
Careful with cheap holster. You want your holsters to be firm. If you squeeze with your fingers you should not be able to collapse it. And as others have said be careful on the angle.
Have you anyone in the area who can loan you want for awhile so you will have more time to observe and talk to other crossdraw shooters?
