Me personally I think the best wheel guns out there are all .45 acp. My edc is a 325 night guard. I wouldn't trade it for any two revolvers in other calibers. I would love to have one of the older 1917's.
Good question! My only 1911 is a steel framed Colt Officer's Model. The 1917 is a hulk of a hand gun. Although the 1911 is more comfortable to shoot(...for my hand), the three inch barrel doesn't give the 1911 near the range of the five and a half inch barrel of the 1917. I backed up to 50 yards and firing single action put six rounds in center mass of the silhouette target.
On the other hand the compact 1911 is a much more comfortable carry gun.
A comparison to a full sized 1911 would be more fair.
