Sig Ultra Feed Test

[Razorwire]

Just a quick reply about magazines (often refered to as "clips" by the unknowing) for the Sig Ultra. I did some research and learned that the mags provided by Sig were made by Checkmate. I researched the patent number on the follower and verified they were made by CM. I purchased a spare mag from KIMBER, and subsequently learned it to was made by CM. I ordered more mags directly from CM. They all work flawlessly. The only difference is is the markings on the base plates (bare=SIG, Kimber and Checkmate). Oh, the new CMs have a black follower.

The SIG ULTRA uses the Wadcutter style mags (parallel feed lips).
