If you look at mine I use foam blocks so I don't have to look for the dot or the sights. It's just like shimming a shotgun stock. If it fits it hits naturally and instinctively.I wouldn't plan on having a need to defend myself with a handgun in a situation where a 100 yard shot was necessary. I sure wouldn't mind having a pistol that I believed was capable of doing it though. I haven't shot my Max 9 at anything like that range but I did recently put a red dot on it & I shoot more accurately with the dot than without. I wouldn't expect to need to use a pistol on a threat at 30 or 40 yards either but if I recall correctly there was a church shooting in Texas sometime back where a person on the church security team did exactly that. He stopped the shooter dead in his tracks.
