EGW Premium Mainspring Housing/Magwell Combo Blue

Machined from: Carbon Steel Barstock
Finish: Blue

Our MSH combo is 25 LPI.

Pins and springs do not come with this part. You can use the pins and springs from your original mainspring housing or purchase new parts from us.

Our premium msh/magwell combo is machined from barstock and held to very tight tolerances. The mainspring housing has a t-slot cut that accepts the magwell. The fit between the two parts is very tight and might require a small tap with a hammer. The width of the mainspring housing is slightly oversized which allows for a tight fit in the frame. This eliminates any type of wobble or play from the msh/magwell.

Warning: This product may be alloyed with trace amounts of lead and other elements which are known to the State of California to cause reproductive harm and cancer. To prevent exposure, do not alter the product by welding, grinding, etc. For more information, go to

EGW Premium Mainspring Housing/Magwell Combo Blue
Purchased and installed this premium mainspring housing/magwell combo. It fit perfectly without any adjusting or fitting. This is an attractive and quality enhancement for my S&W E Series 1911. Another great product from EGW!!
