Trigger Pull: The Umarex XBG and TDP 45 both feature a trigger pull that is moderately to heavily weighted, typical for a double-action-only mechanism. The pull process involves significant take-up and weighs around 8-9 pounds, culminating in a release at the far end of the pull, signaled by a slight clicking noise. If you're accustomed to using lower-priced double-action triggers where the barrel extends upon pulling the trigger, then the experience with these two firearms will be familiar, as they are designed in a very similar fashion.

Accuracy: As of now, the accuracy aspect of these guns remains untested, as I haven't completed my Field Test or Shooting tests. I will update this section with a link to my official Field Shooting Test once it's conducted. Current feedback from others suggests that these Umarex CO2 BB Pistols offer satisfactory performance in terms of shots per CO2, accuracy, and FPS.

Build Quality: The Umarex XBG and TDP 45 share numerous internal components, and I believe they use many identical internal parts. Their plastic exteriors are quite different, with most mechanical parts integrated into these casings, except for the trigger, safety, and magazine release. The primary construction material is plastic, with the exception of certain internal elements, magazines, barrels, and triggers.

Realism: Neither the Umarex XBG nor the TDP 45 CO2 BB Pistols are replicas of any specific firearm currently in production. They are modeled after contemporary mid-sized semi-automatic pistols, though they don't replicate any particular model. They resemble real firearms, but their design prioritizes ease of BB gun construction over mimicking real firearm functionality. Despite this, their simplicity in operation likely contributes to their reliability.


  • Highly affordable, priced around $40.
  • Efficient performance in terms of shots per CO2 and FPS (accuracy pending).
  • Compatible universal metal stick magazine.
  • Well-concealed CO2 tabs.
  • Accessory rails included.
  • Less conspicuous construction screws.
  • Reliable and proven design.
  • Favorable SA177 style CO2 hatch.


  • Predominantly plastic exterior.
  • Limited functional parts; most are integrated into the plastic.
  • The double-action trigger can feel long and heavy.
  • Fixed sights; accuracy depends on how well they are aligned.


While my preference leans towards air pistols with more metallic components and functional features, not everyone is willing or able to invest over $100 in an airgun, nor does everyone seek high realism in their airguns. Some individuals prefer an affordable option that still delivers decent performance and reliability. A simpler design with fewer moving parts often translates to greater longevity and fewer chances of malfunction. Depending on your needs, even if you own more sophisticated airguns, opting for budget-friendly models like the Umarex XBG or TDP 45 for everyday use can save wear and tear on your more costly collector items.

Cool little gun

I’d say the gun is too light for a double action only trigger. The gun will jump when the trigger breaks without holding it quite firm. That being said it is pretty fun to shoot once you get the hang of it. Nice and small and feels good in the hand too. Pretty good value if your not quite expecting to shoot bullseyes all day long

Really Great First BB Pistol

This was the first one I bought from this site and I like how competitive the prices are and how fast the shipping was compared to others in the same province.

Excellent value

Excellent low cost BB gun! Gets about 150-200 shots per co2! Accurate, cheap, good power, and efficient with co2 usage? No blow back, which is why I like this pistol as it makes it a very efficient shooter! Buy extra magazines for faster reloading! I bought this for my son, I am buying another for myself it's so fun!

Umarex XBG and TDP 45 CO2 BB Pistol Table Top Review

Umarex XBG and TDP 45 CO2 BB Pistol Table Top Review

377 - 12/4/2021 10:36:18 PM

Type: BB air pistol. Manufacturer: Umarex USA. Model: XBG - TDP 45 Materials: Plastic outer shell. Weight: XBG .9 pounds (400 grams) - TDP 45 .8 pounds (390 grams) Barrel: Metal non-rifled (4.25 inches). Propulsion: CO2 x 1. Action: Semi auto non-blowback, double action only. Ammunition Type: 4.5mm BB's. Ammunition Capacity: 19 round metal stick magazine. FPS: 410. Personally I prefer spending a few more bucks to get air pistols that have more metal and more working parts, but not everyone has 100+ dollars to spend on an airgun or do they need it to be ultra realistic. Some people just want a gun that is easy on the wallet but still offers decent performance and reliability, and to be honest, a simpler design with less moving parts to wear out or malfunction is probably going to give you better reliability at the end of the day. It just depends what you are looking for. Even if you have a few ultra realistic high end airguns, why not pick eitther the XBG or TDP 45 budged minded Umarex models for day to day plinking and put less wear and tear on your more expensive collector pieces ;) Read full article here: Buy the Umarex XBG in Canada: Buy the Umarex TDP 45 in Canada:

Umarex XBG and TDP 45 CO2 BB Pistol Field Test Shooting Review

Umarex XBG and TDP 45 CO2 BB Pistol Field Test Shooting Review

453 - 12/3/2021 2:12:08 AM

This is my Official Field Test Shooting Review for both the Umarex XBG and Umarex TDP 45 CO2 BB Pistols, make sure to also check out my Umarex XBG and TDP 45 Table Top Review for more information on features, specifications and photos. As usual with my Field Test Shooting Reviews I test out both Umarex pistols using my Chronograph and put five rounds through it with each CO2 BB Pistol to get a real world average fps. Umarex claims around 410 and I got pretty close with both pistols using a brand new Umarex CO2 cartridge in each gun. The temperature was not overly warm as we are now into fall here in Canada BC but so there may be room for a bit higher fps out of each Umarex CO2 BB pistol.
