I have a problem with the 1911 as a carry pistol: the thumb safety.
This isn't because it's a bad design; it's because the bloody arthritis causes my thumb to sometimes have problems working it. Particularly on a draw stroke. So did a little digging, and finally decided to order one of these
for my pistol. It's a safety with the lever your thumb works located much lower than the standard. I dug around for reviews, and overall they were good*.
Hopefully, this'll be a good, durable part and will take care of the problem.
*There'll always be some bad ones, on anything, and there were only a few bad ones on the construction/mechanical side.
