Sig alluminum frame life

Ok what can one expect from a Sig Alloy frame for round count. 20K is what I generally hear but some claim far more than that. What say you all?

If you lube them with grease like you are supposed to they average 40-60k

A lot will depend on which caliber Sig you are talking about.

member surf got 100k plus from their .40 s&w.

Why not Sig?

I’ve worked on West German Sigs that have over 60k rounds through them at FLETC. The old frames are more durable than the newer frames, so I’d expect less of a service life out of new alloy frames.
