But, we were asked what we don't like, and I do not prefer the weight of my RIA full sized 1911 10mm.
I've never seen an aluminum frame 10mm. I guess it all depends on how many rounds of the full power stuff you would intend on cycling through the gun as as to whether or not it would be a good idea. 10mm is hard even on steel frames.

No one offers aluminum frames aftermarket, which really bums me out. Rumor has it that Caspian will do a batch from time to time, but I've yet to see one.
