I have come across a couple of bargains.
My first introduction to really cheap, but useful pistols was the BERETTA model 82 Cheetah pistol in .32ACP. These were police (I think Israeli) trade-ins and I bought the first one for $169.00. They are as reliable as you would expect a BERETTA to be, very easy to control as they are a large gun for the .32ACP and accurate. They convinced me that a .32ACP is an adequate defensive pistol, if something bigger is not available. Just remember to aim carefully.
The second was the STOEGER Cougar 8000/8040 series. These are clones of the BERETTA 8000 series of pistols, discontinued by BERETTA, in Italy and then put into production by STOEGER (a division of BERETTA), in Turkey.
I have found them to be just as reliable as my BERETTA 8000D pistol and in the case of the .40 caliber 8040 pistols, they both cost under $300.00. They handle even the heaviest loads, though the shorter 3.6 inch barrel makes a bright flash with the 135 and 155 grain, high velocity loads. Handling is good, recoil controllable and accuracy more than adequate.
My third bargain was when I was up in CANADA. I bought a pair of Belgium made BROWNING Nomad pistols for @ $300.00 They are beautifully made and shoot well.
My other big bargain was with revolvers. I bought a S&W model 15 with a 4 inch barrel and HOGUE grips for .$279.00 It looked like hell as the Florida prison guards who used it, scratched their names or I.D. numbers on the sideplate. On the other hand, the trigger was smooth, so I took a chance. I shot it at the range and raced back to a 6 inch for the same price. It really shot well and I have put over a 1000 rounds through each. I have no idea how many went before, but loaded with FEDERAL HST +P 130 grain jhp or DOUBLE TAP +P 125 grain jhp, I have no doubt of its defensive use.
