I have reviewed Low-Pro Products’ Modular Vertical Grip in the past. It is a bomb proof grip with a really innovative integrated wrench feature (see the review for details). It is called the Modular Vertical Grip because it has a threaded tube section that can be removed to convert from a full size grip to a “stubby” sized grip. I basically removed/lost that section since I have no use for a full sized vertical grip and apparently I am not the only one because Low-Pro Products now offers it in a Stubby only version.
It is the same grip with the same great integrated wrench. It just doesn’t come with the threaded tube to convert it to full size and that saves you some money. Check out the Stubby Vertical Grip at Low-Pro Products.
