Ameriglo is the best value for the money - Ameriglo Green Tritium Night Sight For Smith & Wesson M&P SW-801

Rear sight will not fit the MP shield! Front sight with great visibility even with stock rear sight. Even thought the rear sight is not of use to me I will keep the front sight on the gun due to it's easy acquisition and it is very bright. Ameriglo now makes a rear sight specifically for the Shield. I will preferentially purchase Ameriglo over the other manufacturers
Pros: Front sight is bright and easily acquired
Cons: Rear sight does not fit the shield
