Took my gen 4 19 and my smith and wesson 22a1 to the range today. I shot 100 115gr American eagle out of the 19 and 150 40gr out of the s&w. After cleaning both pistols tonight the s&w won't dry fire. Is there something wrong with it? The owners manual says never dry fire your pistol. I can't remember if I've ever dry fired it. Can anyone help me?
