Better than stock but not perfect - Lone Wolf Arms Glock 3 Pin Extended Slide Stop

The first one of these I installed either had some sort of problem with the spring, or there was a problem with the installer (me). Since I usually know what I'm doing with mechanical things, I blame the spring, and in any event, OP kindly sent me out a replacement. The unit is installed and works as intended on my PSA Dagger now. The catch is that the corner of it is not rounded adequately to prevent injury. I had no issues with it at the range, but in an emergency situation, when I would be in a hurry and would probably have reduced fine motor control, I would fully expect to hurt my thumb with it. I intend to file/sand down that corner before I consider carrying the Dagger with this installed on it. So, it works, and I do recommend it (especially for $15), but it could definitely be designed better and should be modified slightly for optimal usage imo.
