Stumbled upon the TG review earlier.

Makes good reading Bob if you are interested in the 70 although you may have read it before?

I find going to the last blog helps chose the previous chapters

I notice his comments on the metalwork;

Extensive use is made of aluminum in the construction of this pistol. The spring tube and outer barrel jacket are made of it, but the true barrel is a thin steel tube inside the outer jacket. The finish is a dark black epoxy that will fool everyone into thinking it’s black oxide, which is what we commonly call bluing.

I had a closer look at mine earlier the colour match is superb it’s all the same nice finish.
