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.

Things I liked: Going to hand this to my hubby; Feral Cat will now do the typing: HI! HI! Feral-Cat here! What do I think...UM.. It's no real P-38/P1 BUT! Like those pistols, It's combat, not target accurate. It looks, feels real. Acccuracy for a smooth bore BB co2 replica can actually be outstanding! ...(with practice, and mastering the heavy trigger), as good or better than a real P-38! It'll punch through aluminum beverage cans past 15 yds(M's) At super close range it might be capable of pest control..IF!!!!..You can master that heavy trigger.

Things I would have changed: OK...If it;s going to be a P-38, it needs to be double action capable. Being only S.A. messes with my head. The trigger is super heavy. It could be lighter;(the PX-4, and non blowback Makarov are hard to beat). But, it's good exercise for those of us who've been shooting so long, we have arthritic trigger fingers! :) - :( While it has alot of punch for a replica CO2, that punch falls off quickly when firing more than 4-5 successive shots. More consistant metering wouud be nice..BUT!!??

What others should know: UM...yeah that d**M slide spring! :D OK,'s really easy upon disassembly even by the instructions to lose that thing. It's mentioned in a P.A, blog which I read, as well as a few post on google. If you must follow the need to do a takedown, take it down in a large plastic bag that'll catch the parts! SERIOUSLY! "IF" you actually catch the spring, putting it back is not that hard. I know, I've done it um...5 times? :D ..And that includes spending an hour looking for it for it the first time after NOT diassembling it in a bag! ;) OK...Um yeah I guess that's about it..LATERS! :D

Things I liked: It looks like the firearm and doesn't have those horrible white warnings. That's it.

Things I would have changed: The trigger is really heavy and rough what makes it difficult to have consistent groups at 24 feet. Umarex should release a new version with light trigger, accurate, really field-strippable, CO2 in the magazine, full blowback and with the same quality of the Luger P08, incorporating the double action and the warning pin when it is ready to fire, like the real firearm. It also deserves a more real metal finish.

What others should know: The first 20 shots, at 24 feet in a rested position, were 1-inch low in a 2.5-inch group most to the left. From the second to the third magazine it kept moving left and going down. On the third magazine I had to correct 1.5-inch high and 1 3/8-inch right to be able to shoot (very carefully) 19 BBs inside the 3-inch circle. You can get 80 shots per CO2, but the last 15 shots already indicate loss of power. The CO2 piercing is not easy, you have to twist really hard to well perforate the cylinder and the slide rattles.

    • 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.
