They need lube, don't run them dry and should handle anything you run through it. I had some weak hand loads that wouldn't cycle my SIG but ran fine through the Girsan clones I have.
I wouldn't say the Girsan is better, it does have all metal guts...no plastic, fit is on par with Beretta, exterior finish is decent but not as durable as Beretta, zero tool marks anywhere on the Girsan, they do look and feel like a quality 92. Grips are slim so the added finger grooves don't make it any larger in the hand. They are true 92F clones....so that puts them a step behind Beretta. The full size and compact blued (non-rail) start at $450, I doubt anyone that handles one would find anything wrong with it.
They are nothing like Rinco SIG clones which are bottom of the barrel, way better then FEG HP clones, only thing I could compare it to is like different 1911 makers...SA/S&W/SIG/STI...they all make a version of a 1911 with some tweaks from the original Colt design but are still quality firearms.
