Umarex SA177 vs HPP Head to Head Shootout

Some "not so new" CO2 Blowback 4.5mm Steel BB Pistols from Umarex, but still popular Replica BB guns that have received a lot of attention and to be honest have to date not had a real "proper" Field Test. So why not put the Umarex SA177 and Umarex HPP side by side for yet another installment of Head to Head Shootouts!

Right off the bat I have to say that one of these very fine Blowback Air Pistols has been retired by Umarex. Word on the street is that some suits from a company that sell real steel semi auto pistols that kind of share a similarity to the Umarex SA177 may have applied some pressure to Umarex and somehow the mold got broken and guess what... No more Umarex SA177's :(

On a positive note, you can still get the Umarex HPP which in my opinion was always a better shooter with a much heavier and snappier blowback along with a very smooth trigger. And yes we have it the HPP for sale in our Canada and US Replica Airguns Stores.

Getting back to this Field Test Head to Head Shootout for the Umarex SA177 and HPP CO2 Blowback 4.5mm Steel BB Pistols. I tested them both out on the Chronograph shooting 5 rounds in each gun using a brand new 12 gram CO2 in combination with 5.1 grain Umarex Zinc Coated Steel BB's. The SA177 average a bit higher at 395 fps while the HPP came in just a hair lower at a respectable 372 fps average.

In terms of accuracy from 30 feet out using a semi rested position (sand bag in the front, standing in the back), Both guns wanted to shoot just a bit to the left and they both had a definite internal tighter group that was about 1.5 inches with some strays that came outside opening the groups up to around 3 inches or so. Both BB Air Pistols worked flawlessly with no problems, again the Umarex HPP for me was more enjoyable to shoot with it's heavy blowback and lighter trigger over the SA177. You can also expect to get around 100 or even more shots out of a single CO2 cartridge.

Make sure to checkout my initial Table Top comparison video for these two Umarex Blowback BB Pistols, it goes back a few years for sure :)

Umarex HPP CO2 BB Chronograph Shooting & Slow-mo

I reviewed this nice little compact Blowback CO2 BB pistol a while back , but I didn't have my Chrony Chronograph or my Casio High Speed Camera, so with all this new technology I thought it was time to revisit my Umarex HPP and see what it could do.

I shot 8 rounds through the Chrony and got an average of 385 FPS which is not too far off the manufacturers claimed 410 FPS. Keep in mind the weather could be a lot warmer!

I also put 8 more rounds into a target from 20 feet away in a free standing position and got a bit of a scattered grouping but I think it was partially my fault because I was a bit surprised at how smooth and light the trigger was. I didn't remember it being so nice and I just wanted to keep pulling it with not too much aiming going on :)

Lastly I shot 10 rounds while capturing the blowback action with my high speed video camera at 210 frames per second, so you can really see the heavy blowback of this snappy airgun.

Enjoy my YouTube Video of the Umarex HPP CO2 BB gun getting Chronographed, shooting at a target and slowed down a bit with my High Speed Camera.


Added the Umarex HPP Blowback BB gun to the Store

I just added the excellently priced and well made Umarex HPP Blowback BB Pistol to the Replica Airguns Store.

The Umarex High Power Pistol (HPP) BB Repeater pistol has a 15-shot drop-out magazine for quick reloading. The 410 fps velocity is quite high for the class of pistol. The crisp blowback action simulates a real firearm. The heavyweight construction of the pistol and integrated accessory rail give it the look and feel of realism. A housed CO2 cartridge in the pistol grip provides the power for the this Sig Sauer looking heavy duty gun.

  • 410 fps
  • 1.8 pounds
  • 3.6 inch steel non-rifled barrel

Related Posts:

Type: BB air pistol.
Manufacturer: Umarex.
Model: HPP.
Materials: Mostly all metal construction.
Weight: 1.8 pounds.
Barrel: 3.6 inches, steel, non-rifled.
Propulsion: CO2 x1.
Action: Semi auto blowback, double action.
Ammunition Type: Steel BBs 4.5mm.
Ammunition Capacity: 15 rounds
FPS: 410
Trigger Pull: This gun has a medium trigger pull, the first 3/4 of the trigger pull actuates the hammer with a noticeable click when the hammer is all the way back and ready to fire. The last part of the trigger pull is much lighter. With practice you will be able to engage the hammer and then fire the gun in a kind of simulated single action mode.
Accuracy: Medium to good.
Build Quality: In its price range this air gun offers good build quality and value, it feels solid and well built and has a very hefty feel for a compact size gun. I would have liked to have seen the magazine made from metal rather than plastic.
Realism: This gun is loosely styled after a Sig Sauer 226-228. It is lacking a cut-out ejection port that would have added greatly to its realism. The grips are also molded into the handle giveing the gun durability but not authenticity. I would have also liked to see a heftier magazine as it's made out of plastic and feels a bit cheap compared to the rest of the gun. I do like the fact that the barrel tip has a large diameter opening making the gun look more like the larger caliber weapon it is styled after. 
Purchased this gun from: The Replica Airguns Store


  • Well priced for what you get.
  • Mostly all metal construction (Except for the magazine).
  • The gun feels really good in the hand and shoots well with a very responsive kick.
  • Good powerful and accuracy for a blowback BB gun.
  • Much better trigger pull/feel than the SA177.
  • Has good power to CO2 usage ratio, can get around 100 shots per CO2 cartridge.
  • Picatinny rail for accessories like Laser sights and tactical lights.


  • Again with the plastic magazine but it is a con after all!
  • Ejection Port should have been cut out to make the gun look more realistic.
  • I would have like to have seen actual rubber grips rather than the moulded in metal ones.

I found this Umarex Blowback BB gun to be a really accurate, responsive and enjoyable gun to shoot. It is very compact yet has nice heft and the blowback action is snappy giving you the feeling of a real automatic weapon. The fact that this gun is so inexpensive and yet delivers great power and CO2 efficiency makes it not only affordable to buy but also shoot on a daily basis.
