Hello Andy, love you reviews.
May be could get someone on Gun smith and show maintained replacing part.
yes I know you going to say repairs should be carried out by a qualified person. but there some of out there been working on our guns for years.
anyway just a thought.
thank you Paul
I have the Umarex Glock gen5 T4E. I successfully replaced the co2 cartridge seals and the punch pin, on both magazine, dust gets in there every so often so needs a clean.
