Other than Springfields use of MIM small parts v. Tisas use of forged parts, no. Materials are comparable.
Both use internals of original design.Do you happen to know which gun has internal mechanisms closest to the original?
I read a lot of things, much of it's bullshit, like this.I remember reading somewhere the original 1911 often jammed due to failure to eject?
Not in terms of reliability. It's meant to prevent denting of the casing upon ejection. If you don't reload it's irrelevant.Do you think the expanded ejection port is warranted and valuable?
I own both, at this point I'd go for the Tisas.
