I tried his carry version, and the rear sight bit the heck out of me. Matter of fact, that is the reason I first tried the regular Warren Tactical rear sight---I liked the sights overall, but the Sevigny rear contour was killing me. The standard WT rear sight angles inward, so I put one of those on the gun, and it didn't bite me at all---and then I found out that I got on target even quicker with them, so I switched over for my competition sights, too.
Both good rear sights, in my opinion. One just bites me.
