Dry firing a 1911 will not hurt it a bit. Relax and get some good practice in. make sure to leave all ammo out of the area in which you are dry firing.
I buy insurance because it protects me.
I buy snap caps so I don't waste precious time asking myself this question.
Insurance companies make money because more people buy insurance than need it.
Snap Caps even more so.
out of all my revolvers and autoloaders the only owners manual that warns against dry firing is my rimfire 22lr beretta 21a... it specifically states dry fire will result in catastrophic damage... so im buying into that centerfire rimfire argument...
