If this is your first 1911, I wouldn't recommend a Officer's size.
The sub-compact 1911 is NOT a good "first-pick" to start your 1911 pattern pistol ownership path.
- It doesn't shoot like a 1911.
- It doesn't feel like a 1911.
- The sight radius is so short that it renders sight shooting useless.
- It is a great CCW.
If you are new to the 1911, if I may be so bold, I would steer you in the direction of a government size (5") in the old-school GI Spec configuration for your first.
Trust me on this one! If you get the Officer's size first, it may be your last 1911.
If you go with the Government size, you will become hooked and start your search for another.
