What options, and where is best value to get CM9 front night sight?

[19Delta]

I have 137 Round thru my new CM9 and I love her! I want to get a front night sight, and I know that Kahr has them. Is there any other brand to consider? Is there a cheaper source to buy them than kahr?

Also, my pocket pistol is a Kahr P380, do I order the same front sight for it? I would love to keep the same sight picture the same.

Thanks guys!
