Dropped right in - Ed Brown Products 1911 Two-Piece Magwell Housing

A true drop-in part, no fitting required, mainspring housing fitted very well in my Sig 1911 without any wiggle. Also great it is a two-piece option, it allowed me to aligned the magwell to the magazine port. A little loctite 242 and it stayed put even after 100x magazine insertions. Also it looked great mitigating the awkward look of the extended 8rd magazine base plates. I liked it so much I bought two more for my other 1911s.
