Lambda Defence GHM9 Thread

[MistakenMexican]

Hi all,

 

I couldn’t find a thread specifically about the GHM9, so I thought I’d start one.

 

I previously had two, the GHM9-G (glock mags) and GHM9-K (MP9 mags).

 

 

 

I sold the GHM9-K recently as I didn’t use it. But I kept the GHM9-G as I use it and want to use it more.

 

I really like it, however out of the box it has one big flaw - it’s gas efficiency. The stock mag only allows you to load 30bbs, which I think was probably strategic when they realised it wouldn’t finish a long mag. It would be fine in the height of summer, I could finish a 50rd mag. But terrible in typical British weather.

 

Recently I’ve fitted a 230mm TBB which is hidden in the supressor and runs into a tracer. However, the muzzle energy shot up from 1.1J to 1.6J.

 

This prompted me to find a way to reduce the muzzle power and increase the gas efficiency. This resulted in a nozzle valve spacer and a short stroke spacer.

 

 

I also found my GHM9 stock had nothing on the end, so I made a knurled butt plate for the stock.

 

 

I don’t have any photos, but there was quite a bit of work involved in getting guarder magazines to fit.

 

I’ll have to wait until winter, but I’m hoping the end result is something that runs all year around!
