Every (well, almost every) Glock user know that this is a reliable pistol, but not without its flaws. Is the frame one of them is hard to say but for several years we have been observing a tendency of the so-called stippling, that is, changing the texture and even the shape of the frame in order to improve the position of the weapon in one's hand and its stability, for example, when holding the gun with wet hands.

Trying to meet the market demand in the USA, POF offers a modified frame for Glock 19 gen4 pistols.

The frame features, among other things, a properly profiled magazine well, which facilitates fast magazine reloading without the need for additional so-called funnels, replaceable pistol grip panels allowing to adjust the thickness of the grip to the user's hand, an extended beaver tail, an undercut and enlarged trigger guard facilitating the use of a weapon in thick gloves and many other features that, according to the manufacturer, improve the ergonomics of the Austrian pistol.

Each of frame comes with an individual serial number.
