American Rifleman has published an article about the TP9 pistol …

For testing, we tried the pistol out with a combination of FMJ ammunition as well as some defensive hollow-point loadings. The pistol was extremely pleasant to shoot, due in no small part to its weight and size combined with its mild 9 mm Luger chambering. Over the course of several hundred rounds, there was a single failure-to-extract malfunction. Apart from that, the testing procedure was uneventful.

Although the TP9 exhibited good mechanical accuracy, the trigger pull was heavy and exhibited some unpleasant stacking before breaking. However, accuracy was still quite good, with it showing a preference for the lighter bullet weights.

I love the TP9 design. Only thing the above pistol is missing is a rock-n-roll¹ switch and a foregrip.
