GSG MP40 9MM... coming soon.
- Thread starter Hitzy
- Start date
GSG and the likes have been basically turning air rifle designs into functional 22lr. Cheap castings screwed together, 1mm thick barrel sleeves instead of true barrels, even in 22lr I would not expect their guns to last a long time. People get the impression they are well made because they are so heavy (the 22lr MP40/STG for example) but as you said, it's all MIM, pot metal, and screws which really turns me off them.
Maybe the 9mm will be a bit more sturdy... I'm not going to be one of the firsts to find out lol.
Yes its "pot metal" technicaly. Its ZAMAK. An aluminum alloy. Zinc, aluminum, magnesium and copper. There's a long list of gun manufacturers that use it. And it's also used to manufacture structural components that may surprise you. Not a hang-up for me at all. MIM is used primarily for the firearms industry, so saying MIM turns you off doesn't completely make sense. Just like you don't see the heads of many golf clubs break in half or crack, you're unlikely to have issues. Modern smelting has resolved the impurity issues that made "pot metal" questionable many years ago.

Quality construction gets me to open my wallet, "cool" doesn't. Golf clubs don't run 30,000psi 6 inches from my face lol.
I still haven't bought into the disposable rifle race to the bottom craze...I still expect my rifles to last several generations lol.
^ I hear ya. It's a $500 gun, and somewhat of a novelty. Obviously not a custom machined CZ. Built to appeal to a certain market. The MIM and ZAMAK process of manufacturing in no way make it unsafe though. As far as lasting generations, maybe, maybe not. It won't rust at least.
But to appeal to your original post, Yes, making it NR, made it pretty ugly. At least we have the option to buy one though.

Buy a Craftsman, Atlas metal lathe and the gears are Zamak. Seems to stand up adequately.
Grizz
I was reading a thread the other day, someone had one of the .22 versions break in half...cheesy materials IMHO.
Not sure how the 9mm version differs.
it didnt break in half. BLS thinks the set screw that held the upper and the lower together sheered off.
you would get the same result if you tighten the set screw part way. yeah , i know not the best design.
