Question on which fiber optic front sight for P10C

[robow7]

Could someone please tell me which Dawson fiber optic front sight from CGW is the same height as the stock front sight on the latest model of the P10C?  My groups are very decent vertically with the present stock sight and I don't want to alter that.  Also, I notice that CGW has two different models or model numbers of fiber optic front sights available for the P10C and was curious what the difference was between them. 
As always, thank you for your input.

Call CGW and ask them, or use their on-line communication service on their website to ask the question.  In my experience, they are very good about responding to such inquiries and helpful in answering questions.

What number is stamped on the front of the factory front sight?  I believe the #3 is 5.75mm tall (including the dovetail)  The #2 is 5.5mm tall (including the dovetail).  I think a .155" tall Dawson (Dawson lists their heights above the slide surface) will match up nicely with a #3, while a .145" will match up with a #2.  Keep in mind that tolerances in the .070" deep front dovetail can effect the final sight height by +- 0.010".
