i'VE HAD BOTH, TOO . The Beretta is much heavier, but very accurate and has swallowed nearly 4,000 rounds with NO PROBLEMS AT ALL. Good ammo, Bad ammo JUNK ammo, never a hiccup!

the sigma was very light, but, as said, not a 'tack driver' thanks to its unique trigger.

after aLOT of shooting, the FS is the one with the permanent home at my house!
