Revolvers are less complicated. This is an important consideration for older folks.
Ever been in line at the gas pumps and happen to watch how older folks regularly get this confused look at everything from opening the gas cap to inserting the credit card, selecting the gas type and then fueling? Half of them look like they've never put gas in their vehicle before. The wife and I were at Sam's Club a few weeks ago and the lines were about four deep. I pointed this out to my wife who at first thought I was kidding... then when she paid attention she said
oh my... you're right , then promised to tell me when I reached that point.
