I don't mind the grip printing a little when I carry iwb. For the most part, only other people that edc would notice or know what it is.to me there really isn't much difference.
the grip/ mag is the same length and that's what is normally the hardest to conceal if that's an issue.
weight savings is about like removing 3-4 rounds from your Government 1911.
Now when you move to a Officer model or defender , now you notice a difference, especially IF its an alloy frame.
I 99% of the time now carry a CZ P-01 but when I do feel like toting a 1911 its normally my Alloy framed officers model. nice flat, light weight, compact weapon.
IF I remember that ones like 23 ounces with an empty mag.
about half the weight of a Government steel frame and a lot shorter as well.
I've looked at a few officers, but there seems to be lots and lots of negative reviews for reliability with 3 or 3.5 inch.
