Diana(Milbro)MklV advice

[Kevin Johnson]

Hi I purchased this lovely Diana(Milbro)MklV pistol off the forum. I'm pleased with the pistol but I am having problems shooting the pellets.
The pistol cocks and loads fine but when I go to press the trigger I can hear air escaping and the pellet is still in the chamber. If anyone can give me some advice will be really helpful as I bought the pistol to shoot in the garden.

It's probably a not sealing adequately piston washer. You will need to take the piston out to assess.
Quite an interesting design, but there are a lot of better plinkers around !

You could try out a,bit of oil into the cylinder so as to get some on the seal .See if that bring the pressure up .If so its the piston seal .

Sounds more like the breach seal doesn't it chaps?

Thanks for your replies most helpful. I have moved the pistol on to a buyer who will sort out the problem.
I like shooting guns but don't dabble in taking them to bits.
