The Hogue Extended Cylinder Release
Many members may not even know that this item exists.
The Hogue extended cylinder release allows a person to pop the revolver cylinder without having to change their grip on the firearm.
It's not really an add-on accessory that I am personally familiar with.
I know that it is being used successfully by some shooters for wheelie-gun competition shooting.
Chime in as to if you think that it may be something useful or worthwhile having on a carry gun.
All opinions are welcome as I have no personal dog in the fight and do not intend to argue for or against it.
