I can only speak to my experience but here goes;
I own two Colt 1911s.
^ My O1070XSE 5" Government
^ My O1070XSE 5" Government before personalizing
^ My O7000D 3" Defender
^ My O7000D 3" Defender before personalizing

With my experience, the steel Government is a great shooter but too heavy for carry.
The Defender is a perfect carry piece but a tad small for my hands.
If I had it to do over again, and may still do it to complete my Colt ownership, I would get the Light Weight Combat Commander.
^ The Colt LWCC Model O4860XSE
