Weihrauch HW45 Review

Composition and Features

The Weihrauch HW45 is made in Germany, with superb build quality and excellent precision. The air pistol is made from wood, steel and aluminium, and is available in silver or black. The sights on the air pistol are made from “TruGlo” fibre optic.


The Weihrauch HW45 is available in three calibre options: .177, .20, or .22. The power source is a spring-piston with settings for both full power or half power. This does result in quite a bit of recoil. Energy is released at 5.9 feet per pound and at a velocity of 600 feet per second. Accurate precision is achieved through a rear sight which is adjustable by micrometer.


The trigger has two stages and can be adjusted to your liking. The safety catch is suitable for both left and right handed individuals. Replacement parts are available for the Weihrauch HW45.


It weighs slightly more than 2.5 pounds, which is quite substantial for an air pistol. Adults will be able to use the air pistol but children may struggle. It also makes it difficult to carry around but it is not too heavy.

Weihrauch HW45 .177 Calibre

This edition of the Weihrauch HW45 is just safe for use in the UK, but really pushes the legal limits. A pellet of 7.0 grains reaches a velocity 600 ft/s. The energy released by the muzzle is approximately 5.9 ft/lb. The trajectory of the peller is quite flat, with increased range and a good penetration. A pellet of 7 or 8 grains is best for the .177.

Weihrauch HW45 .20 Calibre

The range, velocity and trajectory falls in between that of the .177 and .22. It is not a very popular calibre air pistol but many people still enjoy its function. It is a good one to choose if you are not certain which of the three options is best suited to you.

Weihrauch HW45 .22 Calibre

The .22 calibre air pistol is another great choice and fun to shoot. It has a slightly rounder trajectory but provides greater impact energy, approximately 5.9 ft/lb. The velocity is approximately 430 ft/s and the range is less than that of the .177. When the pellet makes contact with a target there is an audible sound but the penetration is not too much.

Weihrauch HW45 Tuning & Accuracy

Weihrauch HW45 Tuning

Initially, it may seem as if the Weihrauch HW45 is not a very accurate air pistol. This is partially due to the strong recoil from shooting, but has more to do with your own abilities. A consistent and precise technique is required to shoot the Weihrauch HW45 in an accurate way. With practice and patience you will find that this air pistol is probably the most accurate one available.


Choosing the right pellet is crucial to obtain high accuracy with the Weihrauch HW45. A pellet which is too large will struggle to be released from the chamber and decrease the power. A too small pellet will leave the chamber but as air escapes it will decrease in accuracy and power. Buy the correct size pellet for your air pistol, depending on the calibre.


Practice makes perfect with the Weihrauch HW45 and with more experience you can shoot accurately and consistently. The way you hold the air pistol has a huge effect on the accuracy. Use a firm, controlled grip if shooting on low power. If you hold it too loosely, the recoil from the pistol will push the barrel upwards and miss the target by about 8 inches over a 10 yard range.


Full power of the Weihrauch HW45 requires a loose grip, giving the air pistol more room to move in your hand. The recoil can then take full affect but will not have any impact on the pellet as it will leave the barrel before the recoil takes place. A tight grip will prevent the recoil and push the barrel lower making the pellet miss its mark.


Practicing with both power settings will give you a good idea of how you need to hold the air pistol. More experience will give you a good indication of your grip and target, so just keep practicing as often as possible. The Weihrauch HW45 is extremely accurate once you are accustomed to its power.


Accuracy is improved with the sights on the HW45. the sight on the front of the air pistol has a fixed position. The sight on the rear of the air pistol can be adjusted with an iron micrometer. The rear sight can be adjusted to accommodate elevation and wind, or to change between full and low power. It only takes a minor turns of the elevation screw. The sights use TruGlo fibre optic, which can be replaced if necessary. It increases viewing during sunlight and is exceptional when it gets darker.


Weihrauch HW45 Moderator

The moderator for the Weihrauch HW45 is an excellent addition to the air pistol. The moderator lowers the power in a suitable fashion for indoor shooting ranges. It has a unique and very secure way of attaching to the air pistol. It does not use the traditional muzzle screw thread.


A crafted male flange is found on the moderator. The muzzle has a matching socket, placed below the foresight. The moderator is then tightened to the air pistol with grub screws. The moderator’s design allows for a snug fit and complements the design of the Weihrauch HW45.


The Weihrauch HW45 air pistol has pristine build quality and shoots very well. The accuracy and precision is excellent once you master the grip on both low and full power. Replaceable parts and regular maintenance will ensure your air pistol remains in good condition.
