1911 Plastic Chamber Thoughts
 

Brands aside (its a WA) I have a feeling that a plastic chamber on any 1911 will eventually crack under the stresses from an aluminum slide. Is this a bad assumption?

If this assumption is correct, I can either get a steel chamber for a good amount of money, or simply shave and polish the lugs off of my slide and add a spacer to my barrel so that the barrel doesn't tilt and I get to continue using my plastic stock chamber.

Any insight?
