The Beretta is more reliable in my experience. The only prob I have ever seen from a 92 was due to limp wristing Really, I've been shooting Beretta's for more than 20 years and have never ever seen a limp wristing incident with one. Due to the weight of the frame, unlike poly framed guns, there is enough mass to allow the slide to cycle even if held weaklyThe Beretta's bbl rides in a unique rail system and moves straight back, and doesn't have any front bbl support... which affects accuracy.Not quite right the barrel does tilt slightly, and during the actual firing sequence the gun locks up tight, before the bullet leaves the barrel, making for a nice tight lockup. Front support is not necessary due to the way the barrel and frame are mated. During assembly the slide is cycled on the frame by a machine to mate the freshly produced parts. If you like military 9mm try a sig226.
If it is truly an Italian B92 I'd grab the 92. If you don't like it it'll be worth something to someone here as all we usually see is US made 92s As much as I hate the plastic parts on the new USA made guns, they are machined to the same specs as the Italian ones.
