Customer Reviews for Umarex HK45 CO2 NBB Steel BB Gun

Brand: Umarex Canada

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.

Pros:

  • 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

Cons:

  • 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.

Dope

Pretty cool. I have a lot of BB pistols. I'd never use one for self defense but out of all of mine a good 30 plus of them.. I'd pick this one for the job. Non blowback, longer barrel, no moving parts (other than safety), packs a punch. A little hefty but I like that. Fits great in my holster.

H&K is the way

I was skeptic about this purchase but trust me it was worth it. I held back from buying it because I really like the blowback action and it doesn't have that. But I can assure you, you'll have fun with it.

Umarex HK45 CO2 NBB Steel BB Gun: Nice training sidearm

We have 2 of these for CQB training scenarios. .Good look and feel,...very accurate. Nice power too (since it's NBB), and large-cap mags. We purchased several extra mags and mounted sub-compact lasers on under-rail, for complete training scenarios. Easily get 5-6 mags per CO2 cartridge.

Not as accurate as descibed

I didn’t find it as accurate as the reviews had stated. I was shooting from 20-25 feet steadying my arm on a railing. The pattern was scattered on the target. I did see o review on you tube that had the same issue. With this model. Maybe I have a ‘one off’ I like the feel of the pistol as it is meant for a guy with larger hands.

HK45

Umarex pistol feels nice in the hand. It's not all metal like it says but looks and feels quite real.

Great BB Pistol for the Price

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! :)
