The Millennium Pro PT145 is almost small enough to be a pocketgun, however it shoots the powerful .45 cartridge. It makes no sense to call it a "mousegun," however compact it may be; therefore I classify it as a "ratgun." Here it is in it's box. I paid $349.00 for this gun, which came with a stainless steel slide, frame rail, two magazines, a magloading device and a plastic brush.
Kel-Tec does not make a .45, however the Taurus PT145 has some similarities to the Kel-Tec P11 (9mm). Both have polymer frames. Both are sub-compacts. Here's a photo that shows them side by side with a Kel-Tec P3AT; and you can see that the PT145 is only slightly larger than the P11.
Here's a closeup photo of the PT145 in my hand, and I have small hands. The three "buttons" below the slide, from left to right are: the assembly pin, the slide stop lever, and a safety lever.
Here is a photo of the rear sight. The front sight is also a plain white dot.
Here's a "bird's eye view" of the PT145. You will notice that the top of the chamber has a mirror finish. This attention to detail is echoed on the interior of the Taurus. The chamber and ramp are polished. The interior was clean when I opened it up after purchasing the gun, and the rails were very lightly oiled. The slide rides on the rails of a steel insert "sub-frame."
Another similarity between the Kel-Tec P11 and the Taurus PT145 is that both have magazines that hold ten rounds. It is amazing to me that the PT145 can hold eleven rounds of .45 ammo, yet have a very comfortable and fairly short grip.
Here's a photo of the Kel-Tec P11 actually lying on top of the PT145. As you can see the difference in size is really quite small.
The grip of the PT145 is about an inch longer than the grip of the P11.
As I stated above, like the Kel-Tec P11, the Taurus PT145 has a metal frame inserted into the polymer frame. The stainless steel slide rides in these grooves in the metal subframe. You will also note the little hole and "spring wire" that holds in the assembly pin, just like in the Kel-Tec.
And a final side-by-side view of the Taurus PT145 and the Kel-Tec P11. The trigger pull weight of the PT145 is smoother, lighter and shorter than that of the Kel-Tec P11, and it is therefore easier to shoot straight. I don't have a scale, but I'm guessing the trigger pull on my PT145 is around 6-8 pounds.
