I want get into much detail. My neck and lower back have several Bad Discs. I would like to know are the all steel 1911's more durable or just better than the Steel Uppers and Alloy bottoms. I need the lower weight due to my disc. Now CZ's alloy and steel guns are as strong as any on the planet. I want a small carry 1911 and a full size 1911 for the range. See Glocks i shoot actually very well(alot of dry firing +shooting) has greatly decreased my groups. But i've sold most of my all steel guns because of this. To compensate i need some good ideas from whatever you guys think. Some Manufactures would be nice i could look up the specs. on them. All i see local are Kimber's which i want other avenues to explore. Thanks all for any help. At one time in my life i would have chopped my leg off before i bought anything other than an all steel gun. But life and situations in life change. I bought a Glock 34 yesterday now it feels much better than any of my other Glocks. I'm having my Armorer build me some Custom guns also.
