In this Filed Test Shooting Video recorded in the Replica Airguns Indoor Sea Can Shooting Range, I test out the GAMO P-27 NBB CO2 Dual Ammo Pistol to find out what the actual velocity is in fps shooting both 4.5mm steel BB’s and .177 caliber lead Pellets. I also put a full side of each magazine into a paper target setup 30 feet down range again using both BB’s and Pellets to see which ammo type may be more accurate out of the GAMO P-27 NBB CO2 Dual Ammo Pistol? If you are more interested in details and specifications along with some closer up video of the GAMO P-27 then make sure to watch my Table Top Video for it.
Let’s get right to the velocity test of the GAMO P-27 NBB CO2 Dual Ammo Shooting 4.5mm Pistol. Gamo does claim up to 430 fps, I am not sure if this is for BB’s or Pellets or maybe even light weight alloy Pellets. In any case I used standard 4.5mm 5.1 grain steel BB’s and around 7 grain lead Pellets for this test. Shooting 3 rounds of 4.5mm steel BB’s through my Chronograph I averaged 342 fps with the three shots recording 349, 342, 334 fps. Switching to lead Pellets I averaged 288 fps with the three recorded shots of 290, 291, 282. The 4.5mm steel BB’s as you can see shot faster than the lead Pellets but this was most likely due to the heavier weight of the lead pellets.
I was interested to find out if the .177 caliber Pellets where going to be more accurate in the GAMO P-27 NBB CO2 Dual Ammo Pistol as pellets traditionally are more accurate than BB’s but in the case of the GAMO P-27 the barrel is not rifled so there may be less of a benefit shooting pellets for accuracy purposes? The best way to find out is to try it out so that’s exactly what I did. Again starting with 4.5mm steel BB’s I place one side of the 16 round magazine, so 8 rounds into a fresh pepper target setup 30 feet away. I did use my standard shooting stance of sitting in the back on a stool and placing my hands on a sand bag up front for some stability. I did notice the GAMO P-27 NBB CO2 Dual Ammo Pistol liked to shoot a bit high and to the left but I did get around a 3.5 inch grouping and if I removed two shots that where on the outside of the grouping I would have had closer to a 2 inch grouping. Switching to the .177 caliber Pellet side of the magazine I then was able to get my 8 rounds a bit tighter hitting around a 1.5 inch grouping with most of the shots all within 1 inch of each other. Pellets at least for me where the better choice in terms of accuracy.
The GAMO P-27 NBB CO2 Dual Ammo Pistol is a fun little BB and Pellet plinker capable of plinking and action shooting at closer up ranges. I would not want to shoot out much further than 30-40 feet or so but it is accurate enough especially with Pellets to hit pop can sized objects at those ranges. I do like that you have the option of shooting both single and double action as the GAMO P-27 NBB CO2 Dual Ammo Pistol does have an actual working hammer and this does lighten up the trigger a bit more for accurate shot placement when shooting in single action. If a fairly affordable NBB dual Ammo Airgun is what you are after than consider grabbing yourself one over at of one of our Replica Airgun Online Stores, Canada or the US.

Trigger Pull: The trigger pull on the GAMO P-27 NBB CO2 Dual Ammo Pistol is fairly good considering there is no blowback action to pre-cock the hammer. In Single action you can manually cock the hammer for a somewhat lighter trigger pull or you can simply pull the trigger in double action mode which cocks the hammer and cycles the rotary magazine. Both shooting modes are about the same trigger length as the first part of the trigger pull advances the rotary magazine and even in double action the trigger is fairly light but not as light as a true single action trigger.
Accuracy: At this point I have not tested or shot the GAMO P-27 NBB CO2 Dual Ammo Pistol but I do plan on making a Field Test Shooting Video as soon as I can which may be a few weeks as I am attending SHOT Show 2024 next week which will be the focus of my attention for the next few weeks. All I can go on is what Gamo claimed which is an fps of 430 using light weight pellets. When I make my Field Test Shooting Video for the GAMO P-27 I will test it out with regular lead pellets and Steel BB’s.
Build Quality: The build quality of the GAMO P-27 NBB CO2 Dual Ammo Pistol is good overall. Yes it does have a pretty much full plastic shell, but there is enough metal inside to give it a decent 1.5 pound weight which for a smaller pistol like this makes it feel solid in the hand. There is no blowback action which reduces the amount of moving mechanical parts which will make the GAMO P-27 less prone to wear and possible malfunction so I would expect it to be reliable for a long time.
Realism: The GAMO P-27 NBB CO2 Dual Ammo Pistol as far as I can tell is not an exact copy of a real steel pistol in production but it does look like a real gun for sure. It does have a working safety on the slide which is not your typical low cost airgun switch and the barrel is slightly recessed. The CO2 tab is also hidden fairly well at least when looking from the side, so unless you get close to the pistol you would think it was real for sure. That said some giveaways would be the moulded into the slide ejection port and the screw holes on the right side of the two plastic halves of the airgun, but again close inspection would only really reveal this .
Pros:
Has a good weight and feel to it, not cheap feeling in the hand.
Can shoot both BB’s and Pellets.
Has a single and double action trigger/hammer.
Uses standard Gamo/Umarex double sided rotary magazines.
White dot sights for easy sight acquisition.
Realistic safety lever on the side of the slide.
Picatinny rail for add on accessories.
Recessed barrel adds to realism.
Claimed decent high velocity of 430fps.
Cons:
Mostly plastic external gun.
Sights are fixed so no adjustment.
No blowback action if that is important to you.
Comments:
As far as I can remember, I have not seen an Airgun that uses this type of double sided rotary magazine that has not had blowback operation so it will be interesting to see how it shoots. I do expect it to be a bit more powerful than its Blowback counterparts. Overall the GAMO P-27 NBB CO2 Dual Ammo Pistol is well built and solid and looks to have a good trigger on it for either double action quick paced shooting or more slowed down accurate shooting in single action. I will for sure be testing it using both BB’s and Pellets, but I have a feeling both will shoot similarly at the end of the day since the barrel is not rifled giving the pellets less of an advantage.
Starting the year off with a Preview Unboxing Update Video of three CO2 Air Pistols. One from Gamo is a NBB CO2 Dual Ammo (Pellet/BB) Semi Auto style pistol called the Gamo P-27. The other two are for Crosman and are both Revolvers but from very different aras. The First Revolver I look at is the Crosman SNR357 which is essentially an early revision rebranded Dan Wesson in a 2.5 inch barrel. You can use either .177 caliber pellets or 4.5mm BB’s with it loading them into the 6 shells that come with it. A new comer I have never seen is the Crosman Fortify styled after the classic Single Action Army Colt 45 old West Revolver. Unlike many of today shell loading CO2 Revolvers, the Crosman Fortify has an internal tube fed magazine with a spring follower that holds 18 4.5mm Steel BB’s.
Watch my Preview Unboxing Update Video where I take a quick look and go over some basic specifications along with my initial thoughts…
