there are many...
what makes the difference in them? personal preference? |
| Not sure I am understanding what you are asking, but different heights will change POI. I am in the middle of this since my G21 POI is very high, like 10" high at 25 yards. I had 3 different shooters confirm this. I went with a taller front sight and shorter rear sight. So to answer you question, height will affect POI. I used the Ameriglow website sight correction calculator to figure out what I needed to change the sight heights to. |

Factory has a bunch of different ones, so the aftermarket does too. Most Glocks are regulated for a 6 o' clock hold, some shooters, especially competition don't like that.
There's a nice explanation here from 10-8. |
