Just want to point out that there are other factors to recoil that may need to be considered as well. Just having a heavier gun may decrease distance that a gun would be pushed rearward, but it may not make it more controllable. Weight distribution and bord height over the grip can have a big impact on muzzle rise and overall controllability.
Just as an example I have three different types of .45 ACP handguns. 1911s, Glock 21, and Sig 220. A friend has a HiPoint in .45. My 1911s have steel frames as well as a low bore axis, and use single stack mags. The Glock 21 has a polymer frame, but a bore axis that is equally low as my 1911, and a double stack mag. The 220 has an alloy frame a single stack mag and the highest bore axis of my .45s. My friends HiPoint has a polymer frame, single stack mag, a high bore axis and is a blowback action which means it has a really heavy slide, and recoil spring and therefore has the most mass, but most of it is above the hand.
The 1911 and Glock have the least muzzle flip and gave the fastest controlled follow up shots even with equal amounts of ammo in the mags. The Sig was noticeably slower for shot to shot times on controlled pairs. The HiPoint was a bit slower still. The Sig may have been able to run a bit faster by gripping higher, but that often resulted in the slide failing to lock back on an empty mag because the slide catch would end up being held down because of its location.
Many people have personal preferences in gun manufacturers and materials. But weight alone, and construction materials are not the only factors in how recoil acts on the gun.
I agree fully though that in a strict HOME defense gun weight may be considered less of a factor. Stature, age, physical abilities or limitations may bring weight up higher on the list. I also agree that one may not want to start only considering such a narrow list, especially if you have limited shooting experience and exposure to guns. I recommend trying as many as you can before deciding.
Price can be influenced by materials as well. My Sig is more expensive than the Glock, but no more functional (it is more accurate though and has a nicer trigger). It is more expensive than one of my 1911s but less expensive than my match 1911.
I'll finish with my most common advice. If possible, try several guns from trusted manufacturers, and find the gun that you shoot best. I have a fairly short list of guns that I just plain don't like. I have a few that I recommend that people include in their sample population if they can try them before they buy them, as well. Smith and Wesson, Colt, Sig, Beretta, Glock, H&K, and Ruger all have new and older models of guns that have proven to be solid performers. On the budgeting end side, one can look for used police trade in versions of the above. There are more out there, too. These just are the first ones to come to mind.
