So, people like Jerry Miculek who out thousands and thousands of rounds down range every year aren't gaining anything with an upgraded trigger? Okay
While it is true that people can learn to shoot a stock trigger well, saying that upgrading a trigger doesn't help is nonsense.
I'm much more worried it being used against me that I shoot competitively at card board silhouettes than the fact that I have upgraded my Glock trigger to make it more crisp.
