A lot of people seem to0 have trouble with the Heine Straight 8 sights. I personally like them. It seems to me anyway easier to stack two dots than line up three in a hurry. But that's just me. I was really happy wit the fit and finish of the ones I bought and the others I've got to see and shoot. For the money it's hard to overlook the PT1911 in my opinion.
I like the sights but they don't glow...my main problem. The CZs sights glow...
I want to be a ball turret gunner.
