I bought a heavier spring for it when I first got it but found it didn't run right with the heavy spring and it shows no issues with the stock spring. Not that there may have been issues with others just sayin mine is doing fine. may not have if I had been able to continue to compete as I was just getting going with the 10 when my back put me out of the game so it barely got warmed up before it got put away probably for good as a competitor. Its still gets a lil play time around hunting seasons and winter time CCW. If I had gotten 5000 plus rounds through it I may have had problems as described but at a guestimated 1500 or less its just fine.
How old is yours? If you google "EAA Witness 10 mm Slide Cracking," you will come upon a number of different things. One of which is a report in another forum that there have been changes to the slide design in the last year or so. I'm not really up to speed on the latest mods by Tanfoglio.
I maintain that the OEM 14 lb spring is entirely too weak for 10 mm use. YMMV. I run a 16 with .45 with no issues. An 18 worked OK, but it was very likely overdoing things since my ammo is fairly tame.
