There is nothing natural about gripping a pistol and pointing at things with it.
There is nothing wrong with the Glock grip angle or a conventional grip angle.
One is not better or worse than the other there is just what you are trained and acclimated to.
Glock is one of those platforms that is easy to shoot at a low to medium level and slightly more challenging to shoot at a high-level. If you want to shoot Glocks well I.e. at high-level, you need to stick with shooting Glocks.
If you try to flit around between Glocks and other pistols with a different grip angle, one of those is going to be your default setting.
If you began shooting with something other than Glocks or you’ve been away from Glocks for a while and they “point high” that is a software issue not a hardware issue. A bit of dry practice presenting the pistol and the issue goes away. There’s trained and there’s untrained anything else is b******t.
