Ive carried quite a few. Of coarse every one starts out with the Clint Eastwood symptoms. Bigger the better. "Stopping power you know! LOL! Then the next is light but still large where you drop to a 4-5 lb 40-357-38-45 area. Still maybe a pound or two lighter. Ive also carried a 22 which is the bullet police are most afraid of. If a shot hits the lungs its more liable to scrambled every thing in your body bouncing around. Bigger guns make thru holes and unless hitting and organ or vital area less likely to kill. But will drop you all the same.So a 9mm or .380 is usually what every one ends up setting on. Now I chose the 9 mm compact thunder for obvious reasons and some not so. Its a plain black gun made to serve a purpose It's light weight for sure and fits my pocket pretty nice. But on the other side it still has the feel of a heavier hand gun. So repeat shots are really a lot faster then a real light compact. Haven't had or even heard of a miss fire with one. Least not shooting good ammo any how. They don't advertise much if any so some don't even know of them. They are half the price of a equal gun. Life time warranty to original owner. Used by the professionals there as choice. Her is a small clip from the encyclopedia about the Bersa. So read and goggle for more. But in my mind you will never own a finer gun.
Bersa is currently one of the largest privately owned corporations in Argentina. It produces, among many handguns, the very popular Bersa Thunder 380 and the Bersa Thunder 9 pistols and the Utra Compact series of the Thunder chambered in 9mm, .40 S&W, and .45 ACP.
The company is well known among firearm enthusiasts for producing high quality guns at very reasonable prices and it spends very little money on advertisement. Lifetime warranty coverage is provided to the original owners. While strong and well built, nicely engineered, accurate, visually appealing and very reliable, Bersa handguns are not on par with the most prestigious brands (such as SIG or Beretta for example) when it comes to finishing. However, firearms made by such companies can cost as much as twice or more compared to a Bersa pistol in the same caliber and with similar features. The Argentine company is often influenced by the German firearms manufacturer Walther in the design of its handguns; the Thunder 22, 32 and 380 are basically clones of the famous Walther PP and PPK while the Thunder 9 and 40 are somewhat similar in appearance and some mechanical aspects to the Walther P88. For many products in the past, a similar source of technical "inspiration" was Beretta. The full size Thunder combat pistol is the standard sidearm of the Argentina Armed Forces (Thunder 9), Argentina Federal Police (Thunder 9), Buenos Aires Provincial Police (Thunder 9) and several other Law Enforcement agencies (Thunder 9 & 40).
The Thunder 22 pistol chambered for the 22 Long Rifle cartridge is widely used among recreational shooters in Latin America and the Thunder 22-6, a longer and thicker barrel version of this handgun, is used in more serious competitions. Team Bersa, equipped with Thunder 9 and Thunder 40 pistols, has won several IPSC matches. The Thunder 32 and 380 handguns sell very well in countries that ban the use of more powerful cartridges for civilian personal defense purposes. The Thunder 380 is immensely popular in the US market as a small and light, easy concealable, high quality and competitively priced personal defense handgun.
