I’ve owned a basket full of 1911 style guns over the years. In 40 years of carrying one I never had an issue with the grip safety. The newer styles with the bump are apparently an upgrade to something that always worked (for me and my XL paws) anyway.
A grip safety adds complexity to the gun but since that design dates back over a hundred years there is some expectation of archaic machine foolery. The companies that have tried to “update” old slabsides have pretty much all gone under for one reason or another but there are more companies than ever making guns that JMB would be quite familiar with. Pretty much as long as the basic silhouette stays the same it sells.
It’s a “cult” thing.
