Can someone post a pic of the correct way to hold a 1911? Every blue moon, I rent one at the range. It has an extended safety. I feel like if I put my thumb on top of the safety its touching the slide which could interfere with the cycling. If I put my thumb under the safety I feel like I'm gonna accidently turn the gun "off" while in the middle of shooting. I'm a major Glock guy and have little experience with 1911s. Thanks.
