I have this holster and the same style for my 92FS. I carry my 84FS in this holster more than any other...it even rides in it when it's in my briefcase. The versatility of the belt loops on both sides and the ability to move the clip to either side to find the perfect fit is great. It is very comfortable to wear in any position.
There was one problem however, the backing on the snap for the thumb break was missing, and I failed to notice until I found the finish on my pistol was being worn off. My 92FS did not have this issue so I inspected that holster and found that there is a plastic cap covering the inside backing of the thumb-break snap to protect the finish. This plastic cap was missing on my 84FS' holster.
I brought this issue to Beretta's attention and they paid for shipping (both ways) and repairs for the pistols finish. They also refunded the cost of the holster so I could order a new one.
No business, person or machine is perfect. It is not that a mistake happens that determines the level of service, but how the mistake is handled. Beretta passed with flying colors and made an even happier customer out of me!
