It won't.
I've fired just over ten thousand rounds over the last two years through DA revolvers, DA/SA semi autos, and striker fired semi autos and have yet to launch one when I did not want to.
To the OP, if you have smallish hands the USP is a brick that does not allow a proper grip.
If you want something more refined than a Glock and want a semi auto, a High Power will do.
