I'm shopping around for a shooters kit for my G43, so far I have found two, one from Rob Applegate, going for 250 Apfeltor Waffenfabrik. Or on Ebay from the netherlands for about 140. Apfeltor steel is 4140 while ebay netherlands is 1018. Any suggestions on which one I should pick? Big price difference yes, but looking at the steel or from experience is what I'm after.
