I've run an AGrip for six years on a Glock 22. It is a work gun. It gets shot a fair amount, handled a lot, carried a lot. The AGrip is non-abrasive. It will not chew up your clothes, nor your hands. It allows a more secure grip on the pistol compared to plain plastic - period.
When your hands are wet or sweaty, the AGrip enhances your grip. When your hands are cold and dry, the AGrip enhances your grip. It just flat out works,
After about five years, I finally pulled my original AGrip off my pistol. Every bit of the fur had worn off and the material had absorbed a lot of skin oil over the years. I planned to take it off and leave it off. One trip to the range changed my mind. On went a new AGrip.
The only downside to the AGrip is that it can sometimes peel back on the leading edge from catching on the holster. I just keep trimming it back until this no longer happens. When the material start to feel a little slick, take a toothbrushe and warm soapy water and scrub it a little, being careful not to get it too wet. That will bring it back somewhat.
