Umarex Walther PPK Blowback CO2 problems

[evo6rs]

Hi, 1st ever post after registering, been a stalker of the site for a while and now I would like to draw on any experience anyone has with my pistol.

I have an Umarex Walther PPK/S imported through Brocock in England.

I have been experiencing problems with the blowback system, whilst it does blowback with reasonable force, the gun will not fire. I have to insert my little finger and gently exert a little pressure on the small rectangular piece of metal below the firing pin. Once I have done this the pistol will fire with blowback once and then I have to repeat the process.

If if helps you understand the problem, when I replace a C02 canister, the gun will fire with full blowback in semi-automatic mode for a handful of shots and then this problkem will kick in.

Is it losing pressure or is there some play in the parts - I would appreciate any advice or pointers you can provide.

Thankyou in advance for any help you can offer.

Hi and welcome to the Forum, I've moved this into Pistols, you'll get a better response in here.

That sounds like part of the safety mechanism which is partly designed to stop the hammer striking the valve when the trigger isn't pulled, for instance if the pistol were dropped on it's hammer.
Not an easy one to diagnose remotely, but pictures could help,

Hi & welcome to the forum.

Your problem could be that the slide needs some lubrication. You could try stripping it down then cleaning out the old lube & applying some Pellgun oil.

Might help
