I have two Thunders. Nice pistols. I think the sights are the same on the older 95 series Bersa and the Thunder. The main difference is the shape of the trigger guard. Mine are fun to shoot, reliable (except with Winchester white box or S&B ammo), and accurate. Trigger is nice for a TDA with a long but not especially heavy DA pull, and a shorter crisp SA pull. Their biggest vulnerability in my experience is the e clip that secures the trigger bar. It's easy to replace, but annoying when it comes off and causes failure to fire. I'm not saying it happens all the time, but one of mine has had to be replaced twice in about 10,000 rounds. Of course, most people won't put that many rounds through one.
