Trigger Pull: The trigger pull on the Umarex Walther P38 CO2 Blowback BB Replica is a bit heavier than I expected it would be as it is a single action only trigger. There is a lot of take up initially but once you hit the release area, the release point is what I would describe as a medium to heavy pull for a single action shooter. With that said it did not seem to effect the accuracy at all and I was able to rifle off quick shots fairly easily.

Accuracy: I shot the Umarex Walther P38 BB Pistol at a target from 20 feet away in a semi rested position, and it performed very good getting just under a 2 inch grouping and very well centered on the target. The sights are not adjustable so adjusting the Umarex Walther P38 would not be possible except by using a modified aim point! My initial Chrony testing puts this BB shooter just under the 400 claimed fps range right in the 380 area which is not bad considering the rather cold day I was shooting on. I also managed to get five magazines worth of shots which is a vert respectable 100 shots per CO2.

Build Quality: The Umarex Walther P38 CO2 Blowback BB Pistol is almost all metal with the exception of the grips which is great to see! I found the fit and finish to also be very good with a nice Semi Gloss paint job that should wear well over time. Interestingly enough the Umarex Walther P38 has a removable barrel so I am assuming that perhaps Umarex will introduce some more barrel length options at some point?

Realism: The Umarex Walther P38 CO2 Blowback BB Airgun is very close to the real steel Walther P38 and even has the Walther P38 licensing on it. What I was really impressed with was the fact that all the mechanical parts do exactly what they would do on the real gun. On some other guns these parts are merely for show and moulded into the gun. The Blowback action, hidden CO2 screw and recessed barrel all help to make this Walther P38 Replica very believable!

  • Replicates the real steel version fairly well with all the working parts pretty much doing what they did on the original.
  • Nice that it has blowback while still gets decent fps and shots per CO2.
  • The Blowback had more feedback then I thought it would.
  • Mine seemed to be very well centered on target and got a good tight grouping.
  • CO2 is very well hidden in the handle.
  • Good weight fit and finish to it.
  • Glad to see a World War BB replica pistol!
  • Almost all metal.


  • Had a rather heavy trigger for a single action only gun.
  • CO2 screw may be a bit hard to tighten for people with sausage fingers.
  • Some people may not like the high gloss finish.


There are few older Classic Airguns out there, especially ones from the World War era! On that topic I would also like to see some old Single Action Army Cowboy Revolvers start to show up in the Replica Airgun market! As I was saying it is nice to see this Classic Walther P38 show up in what seems to be a sea of modern styled airgun replicas. Umarex not only came out with a BB shooting Walther P38, they made it very believable in terms of operation, while maintaining good overall airgun performance. I hope this is a trend that continues in the direction of companies offering more quality airgun replicas of guns from the past.
