Umarex products are absolutely quality and you will have no problems with spare parts. Therefore, I definitely recommend Umarex's HK licensed products in terms of quality and feel. The Hk 45 Compact is definitely quite compact! It fits very easily in the hand. It comes with a different size grip back strap in the box for your convenience. Its weight is 780 g! wow, it's really satisfying. Most of them are made of polymer plastic, but the top slider is aluminum alloy. Despite this, it is quite heavy and satisfying. The magazine capacity of 20+1 is ideal for a compact model. Since it is in the pistol class, its output power is 300-320 FPS. The trigger is very smooth and the click sound it makes when the trigger is activated is quite satisfactory. It feels like you are in control of the grip on the plate under the magazine. His sight is also very successful. You can install 16 mm CCW or a silencer on the barrel. Disassembly is done with a simple apparatus It has a double-action hammer. I'm adding a few pictures about how good quality is the internal mechanism. Umarex does a good job at this!
