I recently shot a friend's Thunder .380acp he has had awhile and has shot alot. It felt large and much heavier than the Kel-Tecs I'm used to. Nice looking, well balanced sidearm. I ran several mags of Federal, JHP 90 gr, Hydra-Shoks he had and it was dead-accurate with minor recoil. The Bersa felt more like a 'real' sidearm (2x the weight, 17 oz, with steel frame) than my Kel-Tec .380 that I love so much and was easily as accurate and reliable with a smooth action and good trigger. The 3.5 in bbl would give it a bit more ft/lbs of energy to tranfer to the target. He is a large man and absolutely 'hated' shooting a mag of the same ammo through my polymer. 8 oz, Kel-Tec.
