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 Dawson Precision Springfield dovetail sight in .160" tall for the EMP or the .180" tall for the EMP4.
If you want to use either the HD-072 or HD-073 front night sights with the orange or green rings, I recommend the HD-005 rear sight for the 3" EMP and the HD-004.5 for the 4" EMP.
