People do get offended

When we tell them their holster  is pretty much useless.

If you can not re-holster without holding the mouth of the holster open with the fingers of your support hand, it is useless, If your spare magazine is attached to your holster, it is pretty much useless. If it has an "adjustable" strap for different guns, it is pretty much useless. There really is a lot of crap being sold as holsters out there.
