Can't speak to the Wilson, but I've been using the Tripp mags based on multiple opinions from some extremely knowledgable 1911 members of the forum and they have been flawless. Customer Service is great as well. The last two mags I ordered a few weeks back were taking awhile so I contacted Tripp, got a response fast (no fault of the company, post office issue), and a follow up response a couple days later to make sure they did arrive.
That reminds me, need to order some 8 rounders from them for my latest acquisition.
