Can't go wrong with these guys. I ran the Sevigny Warren for awhile and liked it alot, my current setup that I like even better is the regular Heinie .125 notch rear sight paired up with an Ameriglo or Dawson .090 wide/.215 high front sight, same light bar proportions as the Sevigny's but smaller. Running a G17, I like Sevignys better on a 34. The proportions there are .150 rear/.115 front.
Yep, Heinie .125 Slant Pro and .090 wide Dawson Fiber Optic on my 34/35. Warren tactical fixed on my 19, fiber optic front. Fast on target and precise enough on the long shots.
