  • Walther P38 pistol
  • Uses a 12-gram CO2 cartridge
  • Semiauto
  • 20rd drop-free BB mag
  • Blowback action
  • Removable barrel
  • Fixed front & rear sights
  • 2-stage non-adjustable trigger

The owner's manual shows you how to remove the barrel. Do NOT go any further than that. Do NOT remove the slide. There's a very long, narrow spring that will quickly, suddenly pop out. If you lose that spring, the gun will not function as intended. The importer does not carry replacement springs if you lose your spring.

The P38 firearm was made famous as the German army sidearm during WWII. This CO2 BB gun by Walther is a faithful replica and will be a fun plinker.

Verified Purchase

Things I liked: Very faithful reproduction. If only the handles were real wood! The real W P38 has a long 2 stage trigger pull as does this reproduction. This one smooth as butter after break-in. After racking slide for 1st shot, BB can roll out of barrel - I have targets set so barrel is always pointing up a bit. For the following 19 SA shots there are no BB roll out problems. The long barrel delivers strong muzz. veloc. (easily 400 fps) and great accuracy.

Things I would have changed: White dot the sights

What others should know: Fingernail polish needed on front sight at least. I did rear also. Be sure to tighten CO2 cartridge puncture screw amply and put small drop of Pellgun oil on every other charge's tip. Buy another 5 mags (inexpensive) so you have 120 shots ready for each CO2 charge at the range.

Things I liked: I have only tested this gun twice. Feels solid and had a fine punch to the blowback. Accuracy not impressive. When changing for the second CO2 it started to leak terribly. Tried to spray with silicon spray and used oil on the CO2 tip but with not success. Finally I decided to dismount it only to find that it was nearmost impossible to put back together agian (watch out - it has a spring at the right side that can easally pop away). After finding a german youtube clip on the internet I managed to put it together but was not able to fix the problem with the leak. Thus only one CO2 canister and then the gun was just to throw in the garbage. I own well over 50 air pistols and this was by far my worst experience. Still I will give it 2 stars as I like that Umarex tries to make historical replicas and that the gun fells nice in the hand.

Things I would have changed: Make the thing work - not leak CO2.

Things I liked: The true to form design of this replica. The stout recoil. The magazine follower locks back and loading is easy. Piercing the powerlet is leak free. The BB's listed in the final section below shot to the point of aim at 6 yards windage wise. I made slight adjustments in how I elevated or lowered the front sight to put them in the center of the bull. All of the BB's named below shot into slightly less than an inch for the majority of shots. The trigger was measured at 7 lbs - 10 the start of use but it felt much heavier. It was really heavy! Several hundred shots later it worked in and became much lighter at 5 lbs - 9 oz. It changed rather quickly so I think a burr or something got worked off. It made a tremendous difference in the shoot-ability. The front sight was very difficult to see for alignment until I carefully painted the rear face white with a Q-Tip dampened with spray paint. My rating of course should not reflect these changes but the pistol has inherent potential.

Things I would have changed: I had some problems with this pistol real quick. At my fourth shot a BB jammed in the chamber. I did not realize it and fired a second shot. I had a double-jam and the pistol locked up and the magazine could not be removed. I moved the take down lever and slid the barrel out of the frame. While removing the magazine, the slide came off and the spring they warn about got loose. I did not lose it but I did not know where it came from. By examination of the details in the frame and slide I figured it out but did not see the proper procedure for replacing it until I had bent it badly attempting to put the slide back on. I thought since there was no replacement spring the pistol may be lost. Instructions should be provided in the Owner's Manual for putting it back in place. I later figured out how and it is not complicated. There is a channel on the right side of the frame that after the slide is installed allows you to slip the spring into its place. Replacement springs would be nice.

What others should know: The problem that caused the jam was that the chamber was undersized. Several premium quality BB's all jammed in later use. When I sized the chamber it was found to be .1570". A BB is nominally .173". I opened up my chamber (the material is a hard rubber) to .1695" and all but one of the 14 BB types I have would now work flawlessly. (I did not attempt to use Crosman as they are not very well made.) The one BB that still jammed is the Marksman Premium, but the Laserhawk works fine. I replaced my damaged spring with one of identical diameter but with a denser pitch and therefore slightly stronger. I put the small follower in the end and slid it into place in the channel. It works beautifully.This spring is not sold individually but can be found in the Wolff Light Duty Coil Spring Pak - English. The stock # is 16075. I found mine at MIDWAY USA. Accuracy is variable from each BB style but excellent from ASG Blaster, Umarex, Remington, Daisy Match Grade (Avanti), and Excite Smart shot.

  • John from USA asked:

    Seen on youtube and online Umarex makes co2 limited P38 in gold/nickel finish with pearl like plastic grips but why cant we get one in the USA? it is UK and local only shipping

    • Tyler from USA:

      I have never seen one in the US, probably made specifically for the UK/European market. Or the US arm of the company didn't have an interest in bringing it in.

  • Stephen from USA asked:

    Do actual P38 wood grips fit on the C02 model?
