Sig Sauer P250 & P226 - Umarex PX4 Storm - Gamo P25 & MP9 Comparison

No Comments

Make sure to watch my YouTube video for this Comparison Review as I go into a lot of detail about the similarities and difference with each of these CO2 Blowback Pellet Guns.

Here are some of the main Similarities when comparing the Sig Sauer P250 & P226 - Umarex PX4 Storm - Gamo P25 & MP9:

  • All of these CO2 blowback pellet guns are made for each company in Japan (I am assuming from the same factory?)
  • All of the listed Pellet Airguns shoot .177 caliber pellets (Can be Alloy or Lead)
  • They all have double sided rotary stick magazines that hold 8 rounds on each end for a total of 16 shots per magazine.
  • All of the Airguns use 12 gram CO2.
  • All compared pellet guns have Blowback operation.
  • All of these pellet pistols have single and double action triggers except for the Gamo MP9 which is single action only and needs to be charged on the first shot.
  • They all have rifled barrels.

Here is where we find some key differences between these CO2 Blowback Pellet Pistols:

The FPS Velocity for each Airgun: 

The weight of Each Pellet Gun:

The Barrel Length for each Air Pistol:

The Main Build Materials for each Pellet Pistol:

Is the Ejection Port Cut Out? 

Is it a Replica of a Real Steel Gun?

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


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.

In terms of shooting performance, both Umarex PX4 Storms performed very similarly, getting almost the exact feet per second rating on my Chronograph. (First generation had 363 average fps versus current version with 357 average fps). By the way I was using 7 grain flat head RWS pellets for both my Chronograph and target testing.

Both pistols also shot really nice groupings, form side to side there was about a 1.5 inch spread but vertically the groupings seemed to get more into around the 3 inch spread range. This could be perhaps because of shooting heavy grain pellets and the variation in fps which will make a heavy grain pellet drop a bit. My first generation PX4 did seem to shoot a bit higher on target then my current generation PX4 which seemed to like to shoot right in the bulls eye area.

Both pistols have a really nice snappy and hard hitting blowback action especially using a new CO2, they are also a bit on the louder side so be aware of this when shooting in residential areas. You can expect to get around 4 decent magazines or 64 shots per CO2 but there will be some power drop near the end of the CO2.

Overall the Umarex PX4 Storm CO2 Blowback Pellet Pistol is a great looking replica of the real steel PX4 and also performs very well in terms of power, accuracy and shots per CO2 for such a hard hitting blowback pellet pistol. It is is also one of our best priced Pellet Pistols in my books for value versus cost spent.

KWC Luger P-08 Back in Stock - Umarex TDP 45 Tac - Beretta PX4 - Update Preview Video

1 Comment

Some updates to share with you, first off we have the KWC Luger P-08's back in stock. And that would be for the 6mm Airsoft and 4.5mm Steel BB versions. get them while you can, our last batch ran out fast!

I also show off the Umarex TDP 45 Tac which is the tactical version of the TDP 45 and comes with the additions of a threaded barrel that houses a removable mock silencer, a sight rail for adding a red dot scope and a removable laser. All of this for around $60 so great value for sure!

I also wanted to revisit the Umarex PX4 Storm Blowback Pellet Pistol since I reviewed this gun way back and my personal Umarex PX4 Storm was one of the first to enter Canada and as I saw with the Umarex CP99 Compact, Umarex made some slight tweaks to it and improved the overall performance. So perhaps a side by side comparisons in order, first generation versus present generation.

I also mention the ASG Bersa Thunder Pro 9 because I actually forgot I had reviewed it and was going to review it again. Guess I am either getting old and losing losing my mind or I have made way too many videos and can not keep track anymore, perhaps a bit of both, anyways ignore that part of the video, you can already watch my Table Top Review and Filed Test Review for the ASG Bersa Thunder Pro 9.

Gamo PT-85 vs Umarex Beretta PX4 Storm Head to Head Shootout

No Comments

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.

Make sure to checkout my other posts for my Umarex Beretta PX4 Storm and also the  Gamo PT-85.

Watch the video below to see the Beretta PX4 Storm CO2 Blowback Pellet Pistol go head to head against the Gamo PT-85 CO2 Blowback Pellet Pistol in both a test of the feet per second performance and accuracy shooting at 30 feet using a semi rested position.

Added the Umarex Beretta PX4 Storm to the Store


A few more Store product updates... I just added the Umarex Beretta PX4 Storm to go along with the PX4 Storm Recon we have in our Replica Airguns Store.

The Beretta Px4 Storm Recon air pistol is not only a BB gun, but a pellet gun as well. It will shoot either projectile from its revolutionary dual-ended magazine. This 16-shot repeater will have you shooting as fast as you can pull the trigger. There's an 8-shot rotary clip on one end of the stick mag, and another one at the other end. Since it shoots BBs or pellets, you'll have more flexibility with ammo choice.

A 12-gram CO2 is easily loaded into the grip and gives you plenty of shots before you need a refill. There's even an accessory rail under the barrel. Like the handgun, it has real blowback action, it really kicks, giving you a feeling of power that most airguns only hope to achieve! Once you start shooting, you won't want to stop, so get lots of RWS pellets, BBs and Walther CO2.

  • .177 Pellet & 4.5mm BB
  • CO2 Powered
  • 16 round magazine (8 on each end)
  • 380 fps
  • 1.6 pounds
  • 4.5 inch steel rifled barrel
  • Single and double action
  • Blowback
  • Metal slide - polymer frame
  • Tactical Rail Mount

Beretta CX4 Rifle & PX4 Storm Tactical Pistol Added to Collection


Related Posts:

I acquired a couple new CO2 blowback pellet guns to add to my Airgun Collection! I say new but they are actually used (Barley!). I got them off of a friend who wasn't really using them any more and he figured if he wanted to shoot them, he could always just drop by. Buying second hand is a good way to purchase items if you can find what you're looking for and if it's in good condition.

The Beretta CX4 Storm is a German made true-blowback semi-auto CO2 air rifle that uses 88 gram CO2 tanks and has a 30 round removable magazine. The claimed FPS is rated at 495 although I suspect it shoots under this. It is nearly identical to it's 9mm and 40 Cal brother. It even comes in the same case.

The Beretta PX4 Storm Tactical Pistol is basically the same gun as my Non-tactical Beretta PX4 Blowback Airgun but in two-tone and with a few added accessories such as a Silencer, Rail System, Red Dot Sight, and Tactical Flashlight. It uses regular 12 gram CO2 cartridges, has a 16 round magazine with a claimed FPS of 380.

As with all of my air guns, I plan to eventually review these two nice additions to my Replica Airgun Collection!

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 acceptation is the safety lever which has been repurposed from the Umarex CP99 Compact BB Blowback Airgun.
Purchased this gun in: The Replica Airguns Store.


  • 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.

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 decent accuracy and you can expect about 60 good shots out of a CO2 cartridge. At well under $100, this replica airgun is a great value and a nice addition to any airgun enthusiasts collection.
