stress relief cuts on 1911 10mm's?

bamaranger · March 29, 2020, 09:06 PM

When Colt introduced the Delta/10mm, they suffered some frame cracks, and mitigated the issue by opening the notch in which the the slide lock lever travels. Some questions:
-Does Colt still manufacture their 1911/10mm's with said stress relief cut?
-How do other 1911 mfg's deal with the frame stress issue with the 10mm?
Can anybody that list pistols with and without the cut? Particularly interested in RIA, Ruger and Rem.

All Colt 1911s, other than historical military replica models, have the relief cut.
Can't help, regarding what other companies do, or have done.
