I've owned three .44 Magnums, still have both 4 inch Smiths. One is a 25.5 oz. 329, and the other is a 43 oz. 29. I owned a 1006 smith for over 20 years. A bit heavier gun. I've shot a couple of 39 oz. 1911, 10 mm's.
No comparison. The 1911's were sharper recoiling than those than those 1911's in .45 ACP. But, with hot 185 gr. loads, say 1150 fps. w/ a 185 gr. HP, the difference was pretty small.
The 43 oz., all steel 29 is much heavier recoiling than the like weight 10's. On the order of 50-100% more. Alot depends on the gun's fit to one's hand.
A couple of other things. The 10mm has no where near the sharp muzzle blast of the .44 magnums. I had a 43 oz. Smith 57 with a 4 inch barrel for a few years. 15% of the .44 Mags recoil is about right.
Still more. The 10 mm is not "hot" loaded by most factory ammo companies for good reason. As a hand loader of some 64 years experience, I can tell you is goes critical with any small change in components. E
