Type:BB Pistol Manufacturer:Umarex Model: HK45 Materials: Metal and Polymer Weight: 635 g (1.4 lb) Barrel: Smoothbore Power Source: CO2 Action: Semi-Automatic, Double Action Ammo Type: 4.5mm Steel BBs Ammo Capacity: 20 Rounds FPS: 420
Trigger Pull: Trigger pull on the Umarex HK 45 Metal Slide CO2 BB Pistol is double action only but doesn't feel too bad, it has the traditional longer double action pull but I did not find it to be too heavy and the release point was fairly predictable for me allowing for some good overall accuracy.
Accuracy: I got a bit higher FPS then claimed at 420 FPS with a 5 shot string using a brand new CO2 with RWS 5.1 grain zinc coated steel BBs. From 30 feet away shooting on a paper target using a semi rested posting I was able to place 10 BBs within 1.5 inches, almost close to a 1 inch grouping. The shot placement for me was just a tad to the left and a bit down but several shots hit the bulls eye so out of the box accuracy was really good on this low cost BB pistol.
Build Quality: The Umarex HK 45 Metal Slide CO2 BB Pistol is built fairly basic with few moving parts so there is not much to go wrong, the fit and finish is good and there is metal where it needs to be internally and also the trigger, magazine and slide.
Realism: The Umarex HK 45 Metal Slide CO2 BB Pistol is a very good overall HK 45 replica in terms of size and looks, it has full HK licensing and even has a metal slide and polymer frame like the original real steel HK 45. It is a bit lighter bit not by too much. There is no working slide and the slide catch/release and hammer are molded into the gun. The only working parts would be the safety, magazine release and trigger.
Inexpensive overall decent BB gun
Good accuracy and power
Metal where it matters, slide, magazine, trigger, internals
Nice replica of the original HK 45
Fully HK Licensed
White dot sights easy to sight in your target on most backgrounds
Decent double action trigger
Picatinny rail for accessories
None blowback with a fixed slide
Slide catch/release and hammer are moulded in and none functioning
Sights are none adjustable
Comments: For a rather low cost CO2 4.5mm steel BB pistol, the Umarex HK 45 has a lot going for it! It is fully HK Licensed with a metal slide and metal parts where you want and need it. The accuracy and power are both good and even the double action trigger is very usable. Sure the Umarex HK 45 Metal Slide CO2 BB Pistol is a pretty basic gun with few moving parts but then again simple is sometimes better in terms of reliability. If you are an HK fan and want a low cost well made and good performing BB pistol then checkout the Umarex HK 45.
I'm a complete beginner and just love this pistol! It looks good, feels really nice in the hand and has a good weight to it. It also has good power, no kidding, safety goggles a must always. The only thing that concerned me a bit was the feel of the safety but nothing that turned me off it, just be safety conscious. Overall I love my first BB-gun! :)

HK 45 UMAREX
VERY NICE BB AIR PISTOL HANDLES AND PERFORMS REALLY WELL, LOOKS REALLY COOL AS I ORDERED A ZOMBIE STRYKE TACTICAL LIGHT TO GO ON THE PICATINNY RAIL
Some more new guns I will be checking out, well one is just a different finish of the Umarex Colt SAA Revolver but for sure worth taking a look at in this Preview Video.
All the guns in the YouTube Preview Video and CO2 4.5mm BB Pistols, three are styled after revolvers and one is based on a semi auto modern pistol.
Starting with the revolvers I show off the absolutely gorgeous blued finish on the Umarex Colt Single Action Army BB Revolver and it all I can say is it really needs to be seen in person to fully appreciate how great it looks. I was not expecting the blued version to look nicer than the Nickel version but in my opinion it is my favorite of the two. And that's not to say the Nickel version is not a great looking pistol in it's own right.
I've been waiting a while to see firsthand the Webley & Scott MK6 CO2 BB Revolver and it finally came this week. Another really well built and designed classic Revolver to add to the list of shell loading CO2 BB Revolvers. I was really impressed with the trigger and hammer action, both single and double action feel super smooth and the position of the hammer makes for really easy draw for single action shooting. The 2.4 pound all metal weight give the Webley & Scott MKVI great balance and realism, while the top-break design makes for super easy loading.
Not to be mistaken with the Full Metal Shell Loading Umarex Colt Python 357, I take a look at the more affordable Umarex Polymer Colt Python 357 that fits the bill nicely when looking for a BB Revolver with a nice hammer and trigger, fully adjustable sights, and higher than average capacity magazines than your standard revolver.
Last but not least I look at another fairly affordable CO2 BB Pistol, the Umarex HK45. It's a pretty basic CO2 BB pistol but looks really good and has decent weight with its metal slide. The HK45 features white dot sights, a Picatinny rail, an all metal drop out stick magazine and full Heckler and Koch licensing.
In this Field test Shooting Review I again get out from under my deck roofing and take my Chronograph and target shooting onto the pool patio. I may as well take advantage of the great summer weather we are having and get some rays while I shoot a video :)
Overall the velocity and accuracy of the Umarex HK45 are really good for this low cost BB pistol, the double action trigger is a bit long and on the medium pull, side but that is to be expected. The white dot sights make acquiring just about any target easy which may have helped me in my accuracy portion of the test.
