This product can be used with or without the mag well attached, although there will be a small dovetail below (this does not impair function). The mag well fits nicely in quality frames. The machined checkering gives much better traction than models with cast checkering. This is a great replacement for plastic mainspring housings.
Specs: Machined from: Solid bar stock steel. Finish: Stainless steel or blued carbon steel.Checkering: 25 LPI (Lines Per Inch). Compatible with: Kimber, Colt, and other full-size or commander-style 1911s
