Just bought a safariland 6378-283-411 ALS paddle holster for my G19. Like the idea of an easy on/off holster. Figured I'd get one for my G21sf too. After struggling to get it on I find it comfortable and love the easy access to the pistol and ease of reholstering. Problem...for the life of me I can't get the holster off without almost dislocating both shoulders. Any suggestions before I give up on it? I should mention that I can't really reach the weak hand over for assistance. Have shoulder problems. Any trick to doing it with one hand. Wearing a fairly thick 1-1/2" belt with blue jeans. Thanks!!!
