I have had an INOX Tomcat for 5 years now and mine has been a good gun, every time I go to the range even if I’m not particularly practicing with the Tomcat that day I pull it out of my pocket in whatever current state of maintenance it’s in from being carried every day and shoot the ammo that had been carried in it, even dry and full of pocket lint it has always functioned reliably, it’s also pretty accurate for pocket gun.
Most of the problems you hear about with this model are with the early blued Tomcats, the narrow slide didn't have enough weight to absorb the recoil energy so it would cycle to fast and with too much force and beat the frame to death.
The INOX (stainless) Tomcats and the newer blued Tomcats have a much wider slide and do not have the problems the early ones did.
However there are still older blued Tomcats in dealer/distributer stock that have just not been sold yet, they are now kind of mixed in with the new Tomcats and it wouldn’t be uncommon at say a gun show to see a new (older narrow slide) blued Tomcat at one booth and a new (newer wider slide) blued Tomcat at another.
Beretta should have recalled the older blued Tomcat and updated them with the new wider slide rather than just addressing the ones that get used and come back with a cracked frame and a confused and/or pissed off owner.
I guess the bean counters at Beretta figured it would be cheaper to hope most of the old blued Tomcats just fade away but things like this damage the reputation of both the model and the manufacture.
Here are some comparison photos between my INOX slide and a older Blued slide.
