Terrible if you use a strong grip
I bought this with the intention of solving the issue of a short grip coupled with reloads. For me having the ability to reload without using the "tactical tea pinky" method was the selling point of the design. The actual adaptor is very well made and finished - top quality. However, after following the supplied directions for installation and test firing one magazine I found a flaw in the design. The flaw is sadly a necessity for the design to function at a basic level: in order to facilitate a drop-free design for the magazine the pronounced lip of the device is required, otherwise the toe of the magazine floorplate would hang up on your fingers. This lip acts as a leverage point if your hands are large enough, add a strong grip in place and this lip allowed me to pull the front mounting point out of the frame and bind up the magazine as well as (very slightly) damage the frame in doing so. The front mounting post is actually a screw that grips the polymer of the frame, this actually removed enough material that the screw no longer had anything to grip since that material pulled out with the threads. To summarize: Installed, test fired 8 rounds using a strong shooting grip, product failed due to design coupled with my hand size and strength of grip used.
