I have owned a Bersa Thunder 380 for a couple of months now, and if I had only one thing to say, it would be that I am very pleased with it. So far, I have put some 500 rounds through it without a single problem.
Inexpensive, reliable and accurate, it'll eat practically any standard-pressure FML and JHP factory load you feed it, including Federal Hydra-Shoks. But I wouldn't try reloads or +P ammo, as they are not recommended by Bersa and may void the warranty.
Incidentally, this was my pistol of choice for the Texas CCW proficency test. I scored 235 points with it---right out of the box!
That's right, I had never fired it before (The risk of erring on the short side of 170 and not passing the test due to a malfunction or my lack of experience with it was a deliberate attempt on my part to bolster my confidence in the face of uncertainty). And yet, I was stunned by its awsome performance. Made me look like I'd been training with it for years! Almost as if it knew where to put the bullet!
(The rear sight on mine seems a gnat's whisker off-center; but for all I know, this could be an intentional factory adjustment---one of those quality control things necessary to compensate for tiny misalignments in the barrel or something. The sight radius, on the other hand, is so short that you can easily miss your target at ten yards if you don't align the dots with your strong eye. But then, that's what you're supposed to do.)
Compared with the Walther, I would say this is one of those typical blue-moon instances where South American craftsmanship beats German engineering hands down. Or is there any difference? Whatever the case, I think it would at least be safe to say that the Bersa is what you'd normally EXPECT the Walther to be---at half the price!
One word of caution, though: The slide-mounted safety lever is small---too small, in my opinion---and may feel a bit stubborn without adequate lubrication. I practice drawing my gun as fast as I can under simulated stress, and still fail 25% of the time putting it in firing mode (i.e., flicking the safety upward with the grip-side of my thumb). Where seconds count, this is not very reassuring. But that's me. Someone else might have no trouble at all.
As far as concealed carry goes, those of you who are considering using the Bersa as your primary or backup weapon are probably wondering if it's a good stopper. I don't know, I've never dropped mine in the tub
Seriously. You've heard it before: stopping power is more a function of placement and bullet type rather than caliber. A wimpy .22 round-tip through an eye socket or between the forth and fifth rib will wreak more havoc than a ferocious 158-grain .357 magnum hollowpoint though the tip of a finger. Personally, I don't think any alley-ape who doesn't relish the thought of plucking a 90-grain lead mushroom with a hard center post out of his frickin' a** will want to pluck out two or more, if you know what I mean. But if you still want 100% stopping power, get a rocket launcher.
All things considered, Bersas are fine little guns.
Buy one. You won't regret it.
