Hi all. Bought a factory re-furbed G22 yesterday. This is my first Glock and I can't wait to get to the range. First thing I did was put in a factory extended mag release button. (I knew from shooting other Glocks I would want this mod). This is my new carry gun and I will be using it IDPA, which I became addicted to last summer. (Have been shooting a Beretta 96 Brigadier.) I am doing my first three gun match next month and can't wait. My question is this: If I file down the sharp corners off of the new mag release button will that bump the gun out of SSP? Any input is appreciated. Thanks, Ozz.
