[Tuthmose]

My apologies ahead of time for what is the mother of all necro-posts, but my question was heavily tied to this thread's topic . . .

Are the newer (as in, I got one two weeks ago) ProG4 slides reinforced to prevent this kind of damage when using a metal chamber? I do see a beefy-thick vertical lug on the slide wall opposite the ejection port, which doesn't appear to be present on Illusion's labeled image on the first page of this thread. Does that mean it's the new-and-improved version?

I have a Tanio-Koba outer barrel I was planning on using with the ProG4 slide, but I surely don't want to drop that in there if it's gonna wreck my slide in three or four mags!

Any input would be appreciate. If needed, I can take a pic of the new slide's insides when I get home this evening.

Thanks in advance,
Tuthmose
