This is why you dehorn a 1911 (i.e. round the edges).1911's are great and I love them. But most seem to have pretty sharp edges and things that get in the way when I carry. For that reason I went with a Ruger P345 as my everyday carry piece. Now if you're not interested in carrying your .45 then a 1911 is your best bet. I really like the Ruger SR1911.
Any gun that isn't properly dehorned is going to have sharp edges that will catch on things.
That said, a full size 1911 is fairly slim and if dehorned - is a wonderful firearm to carry. I carry my full size 1911 all day every day and have nary an issue .
