Umarex H&K P30 misfiring

That is a great result. Please keep us updated.

Just heard back from Bisley. They can’t locate a fault. They have fired 100 pellets through it single action without a misfire. They think the problem may lie with my choice of pellets and recommend Bisley Practice. I am sceptical as I tried a variety of pellets, domed and flathead, including Pro-Target Trophy, Milbro Caledonian and Excite Econ, all carefully seated and all with misfires. A mystery, but still very pleased with the helpfulness of Bisley and Umarex.

I am sceptical. In my experience, the three main faults on Umarex pellet firers are (a) worn, broken or otherwise malfunctioning pawl; (b) broken trigger bar; (c) seals. Only seals are an easy fix.

And on the 1911 only, grip safety issues, given that they took John Browning's excellent firearm grip safety design and made it into a CO2 pistol design nightmare.

Failure fully to index the cylinder can also be a cylinder fault, perhaps that the teeth that engage the pawl are worn. There are definitely at least two types of cylinder "magazine", with different bigger teeth, which suggests an upgrade at some point to minimise malfunctions. But the mags with a P30, as a comparatively recent product, should be of the later and presumably improved type.

It has come back. To my astonishment it came with a bill for £50 although no repairs were made to it. To rub salt in the wound, I test fired it using Bisley Practice pellets as recommended by the armourer and, far from shooting perfectly, at the 13th round it again started misfiring as before. It is an indexing issue, which is a manufacturing fault.
I am still in communication with John Rothery about it and, who knows, they may restore my now somewhat tattered confidence in them.

[Genstabler]

My faith in John Rothery was not misplaced! They have just phoned me and, having seen the photos I sent them, agree there is a problem that their armourer did not pick up. Despite there being no question of liability under warranty, they are going to have another look at it and try to sort it out. I continue to be very impressed with Bisley John Rothery!

[Paul55]

Did it get fixed & what was at fault?

[Genstabler]

John Rothery have now had my faulty HK P30 for the second time for over two months. After their initial very helpful assurances I have heard nothing. Furthermore they are not replying to my emails requesting a sitrep. I think my confidence in their commitment to sorting out the problem may have been misplaced. Very disappointing.
