Mildcustom2, we have 2 of them - one in 20, the other 12 gauge. There have never been any issues with either of them. They have mostly been used for sporting clays, and have seen a lot of rounds, especially the 20.
The Teknys uses shims for adjusting the stock, and you will be able to dial in a little cast-on for shooting left handed (you can adjust the drop and LOP as well). You will not have to worry about the shells hitting you, but you will want to invest in a shell catcher anyway.
On microphone operated trap and skeet ranges closing the action will usually set off the trap. I try and hold the bolt and let it close slowly to avoid this, but be sure it is fully closed!
Try and avoid the "Extra Wood" faux finish models. While the finish seems OK, it looks awful if scratched.
Unlike many semi-autos, the fore end nut on the Beretta never seems to stick. Takedown and cleaning is a snap. Best of all the Beretta barrel(s) throw very nice patterns with all of the choke tubes. Recoil is light.
Balance and handling is OK, the mass distribution is fine for clay targets and pass shooting waterfowl, but even the 20 gauge is too ponderous for the uplands. Everyone who tries them shoot pretty well with them, they are an easy gun to shoot.
Take a minute or two and become familiar with the gun's operating system, and pay particular attention to the little button at the rear of the loading gate - it is perhaps the only source of aggravation for the unfamiliar user.
Overall, I am very satisfied with the performance of the Teknys'. Reliable, easy shooting, easy cleaning, and with an adjustable stock - what more do you want from a semi-auto?
