The only familiarity I have with the Bersa is seeing one at the gun store and it looked way too fat and felt too heavy for the type of carry I was looking for. I have put over 1000 rounds through my Kel-tec P32 with no issues and I have 280 rounds through my P3AT also with no malfunctions or even much sign of wear and 30 of those were Corbon .380. Of course I have my P3AT NP-3'd so it is very slick.
What type of failures have you witnessed with the Kel-tec?
I know everyone has opinions on specific guns. When I was in the academy, Phoenix PD officers were issued Glocks and my department was issued Smith and Wesson .45's. The Smiths were the biggest POS's ever and I would not have trusted my life to that gun. I can't tell you how many times we waited on the range because one of our Smiths took a dump, class 3 malfunctions included. The Glock shooters always stood there waiting on us. The second I graduated, I bought a Glock and carried one on-duty of one caliber or another for the next ten years.
I'm not saying my Kel-tec is my only gun, but there is rarely ever a time I don't have it. Can the guys trying to conceal a Glock 27 or 1911 say that? I carried a Glock 27 for years in a fanny pack that screamed "gun insided", but the second I had to dress up where a fanny pack was no longer acceptable, even my ankle holster was a pain. My Kel-tec is much like my wallet, its in my pocket when ever I'm out of the house and its there much of the time I'm in my house.
Would I rather carry my Glock 22C with 30 round mag all the time? Yes. Even more so, would I always like to have my AR-15 with Surefire Tactical Light loaded with Corbon .223 ammo on my shoulder? Yes. Do I anticipate many run-ins with a pack of angry Hell's Angels when I'm at the mall with my wife? No. Do I think it's likely that 20 gangbangers are going to try and jump me when I'm walking from my car to America West Arena? No. Do I think I might get in a situation that might require me to defend my myself or family against one or two attackers, possibly armed? Abosolutely, and it is at those times I will have my Kel-tec, always there.
