I have read many but not all the posts. First off, since competition holsters are available with rare earth magnets to retain your firearm, I am going to say it is fine. So far as the trooper story with the MRI, I don't buy it. The hammer transfers a GREAT deal of engergy to the firing pin. for me to buy that the firing pin was so magnitized that the attraction to the side of the channel and resulting friction was GREATER than the force from the hammer, yeah, sounds like urban BS to me. Even a modified gun for competition transfers a lot of engergy, and bone stock gun, like a PD issue, transfers an obscene amount of force. I don't know the C of F of the two metals, but my guess would be the firing pin would need at minimum 5 or 10 pounds of attraction. MINIMUM probably more like 20 or 30 does not seem very likely when the laws of physics are brought to light.
