Available in .140" wide square notch, .170" wide U notch and both with "T-2" night sight lamp pattern.
I recommend using the HD-004.5 rear sight on both the EMP (3") and the EMP4 pistols. For the front sight, use the Springfield dovetail sight in .160" tall for the EMP or the .180" tall for the EMP4.
Rear Sights for Springfield Ronin, Garrison, EMP-4, the Elite Series and other SA 1911s using a .350" tall rear sight
