Nice contrast - Trijicon HD XR Front Sight

I have installed on my H&K and Sig with no issues. I did have a Wheeler sight tool that worked great, but no filing needed to get started. It's tight and it has to be aligned perfectly. I already had a set destroyed with a cheap sight tool and skinned pistol paying someone else, so get a proper tool and be successful the first time. I have Sig M11 & MK25 and if you want the front sight to stand up and out when you present your pistol, you want the 0.225 so it will be a bit higher and you get on target faster. It's about being first if you have to.
