Trigger Pull: The trigger pull is long and light when in single action mode, there is a slight heavy spot at the begging when the rotary magazine is turned to advance to the next pellet and then another break point near the end to actuate the hammer.

Accuracy: Good, not amazing but pretty good.

Build Quality: Excellent, with a very nice slide finish that is more of a dyed metal rather than painted like most airguns. The non-metal components seem to be very durable and the fit and finish to this gun is outstanding.

Realism: This is a very close replica to the real Beretta PX4 Storm with licensed trademarks and most everything in all the right places. The only real exception is the safety lever that has been repurposed from the Umarex CP99 Compact BB Blowback Airgun.


  • Good reproduction of the original Beretta PX4 Storm.
  • Would make an excellent training gun as it has a similar size, weight, and feel to the actual Beretta PX4 Storm handgun.
  • Blowback action is very firm adding to the realism of shooting this weapon.
  • Good FPS and CO2 efficiency for a blowback Pellet air gun.
  • Nice easy to use sights with white spot markings for quick targeting.
  • Picatinny rail for accessories like a laser sight and/or tactical light.


  • Non-functioning slide release on frame and safety lever on slide.
  • Slide does not stay back after 8th shot so you need to count them off or you end up wasting a few shots before you realize no pellets are coming out.
  • No way to keep the slide back, no working slide release.
  • Safety lever seems out of place and takes away from the realism of this replica.

Comments: The Umarex Beretta PX4 Storm is a very unique pellet blowback air pistol and there are very few airguns that sport all the same features. Not only is it a very close replica of the original Beretta PX4 Storm but it's also a blowback pellet shooter with decent FPS velocity. The Umarex PX4 Storm has reasonable accuracy and you can expect about 60 good shots out of a CO2 cartridge.

Umarex Beretta PX4 Storm Blowback Pellet Pistol First Gen Versus New Head to Head Showdown

Umarex Beretta PX4 Storm Blowback Pellet Pistol First Gen Versus New Head to Head Showdown

8 - 11/24/2021 11:51:35 PM

I originally reviewed my first generation Umarex PX4 Storm CO2 Blowback Pellet Pistol back in August of 2010. Mine was actually one of the first PX4's to come into Canada. Since it has been almost 4 years since I first got my hands on this pellet pistol, I though it might be worth taking a revisit of it and comparing a first generation version to a current generation version of the Umarex PX4. Cosmetically they are really close, I found it hard to tell them apart visually, My first generation had perhaps a slightly lighter colored slide? Other than that they look identical. When I loaded them both up with pellets I did notice that my 4 year old PX4 magazine was tighter in terms of loading the pellets, So in other words, the new Umarex PX4 magazine has slightly larger diameter holes. I don't think this really made much of a difference while shooting, it's just a bit easier to load the newer magazines. Read full article here: Buy PX4 Storm in Canada:

Installment number 2 of my Head-to-Head Airgun comparisons. In this video I compare the replica Umarex Beretta PX4 Storm CO2 Blowback Pellet Pistol versus the Gamo PT-85 CO2 Blowback Pellet Pistol. Both are very similar mechanically and use very similar rotary magazines combined with single action hammers and very heavy blowback.
