I assumed these where aluminum but they are actually plastic. They fit as advertised

Sig P320 Extractor
This is my second lone wolf extractor for P320. The first one fit my slide perfectly. The new one was made .005 thicker and won’t drop in place on my new Sig AXG Scorpion but will on my Sig Pro Cut slide (that’s had 500 rounds through it) so I swapped them and they seem to work. When I called Lone Wolf to tell them what I found they didn’t seem to interested, in fact the first person I talked to tried telling me they didn’t even make Sig parts lol. Long story short they say they cater to Glocks and are unsure of specs or even if the Sig extractors are made in-house. A little disappointing but if it performs like my original it will be fine.
