This isn't a question I personally have to think seriously about any time soon, as I currently only own steel 1911s and I'm not buying a new one in the near future. But it's something I've been pondering and I'm curious about input from others who've been carrying them for a considerable amount of time. I figure there may be enough people here who carry or have carried a 1911 with frequency to get some meaningful results.
What got me thinking about it was the fact that for the specific model I carry, I save (only?) 7oz by switching to its lightweight counterpart model (34oz to 27oz) in exchange for a slightly higher price tag and the maintenance and durability issues that can come with alloy frames (whether or not they actually matter at all or for a given caliber). Also, if I were carrying .45 and chose a lightweight Government model, which I'd be inclined to do for that cartridge, it would weigh basically the same as my steel 4" 9mm, with a few extra ounces added by the heavier ammo.
The main question is whether, considering potential downsides of choosing an aluminum gun (price, durability, desire to then also have a steel training gun when maybe a steel carry gun wouldn't require that dedicated range counterpart), you consider the weight savings of a lightweight model worthwhile, and to what degree. Is it a must have, a nice to have, or a nah, stick with steel?
As a secondary matter, I'm also curious to know if carry location has an impact on this. Does the weight of the gun matter more if it's carried strongside OWB or IWB as opposed to AIWB, where belt tension is generally looser and a stiff belt isn't necessary to hold a gun up?
