I would like to get everybody’s opinion on two materials when it comes to durability. Stainless steel vs anodized aluminum. Both frames would use a stainless steel slide so take that wear into consideration. But not considering weight. Which material would be best durability wise when it comes to rust or pitting and wear and tear. Call it shtf or whatever you want, Im interested in the durability and wear characteristics of the two materials. Or, is there a better material than these that is commonly used for firearm frames?
