If I recall (I lost my last 1911 in a canoeing accident), when you pull the hammer all the way back, it contacts the top of the grip safety, so you can decock it with one hand. It’s dangerous though, because any slip and it’s going to fire, probably not where you want it to.

That's pretty much what old Barry said on “Gun Gripes” when he mentioned customers shooting themselves in the a$$ or leg when they carried a cocked and locked 1911 into the shop for service. They tried to decock as they drew and “Blam”.

It could be the that way for a later model with a bulged grip safety like on a later series. I was thinking of my 1911 and my 1911A1. I’ll have look at them and the Series XXs I have. Thanks.

if the left thumb isn't in FRONT of the hammer while decocking a 1911, somebody needs a refresher safety class
