more POSs
I think most of us have bought at least one cheap gun before, just to see how bad it really was. I was never foolish enough to buy anything made by Jennings, Lorcin, or Phoenix Arms, but I did by that crappy Llama I just described.
My very first handgun was a Dan Wesson .357 Magnum. It was accurate as heck, but the firing pin wore down quickly to where I couldn't get anything but dented primers out of it after about 1,000 rounds.
It had one other significant problem. Those models were known for the ability to switch out different length barrels. Something must not have lined up between the end of the cylinder and the front of the barrel, because every time you would fire it, you, or the person next to you on the range, or even the 2 guys plinking 5 lanes down would get hit with flecks of lead (yes, that actually happened). I tried making sure everything was tight and seated as it should be, but it did not make a difference.
I can think of multiple occasions where lead pieces flew back at me and twice cut the right side of my forehead, as well as the back of my right thumb. And as I said, it ultimately quit firing. It is now a paperweight.
I once bought a new S&W Sigma .40 cal for my girlfriend. It was the one she picked out, and I had read good things about this model in 2 gun magazines, so I purchased the thing. We went to the gun range to test it out. It was a turd. It was essentially a copy of a Glock, just two toned with a nickel-colored slide and black plastic stock and trigger. It had a long trigger pull, which made it difficult for me to get good trigger control, so I couldn't shoot it accurately consistently. That stock and trigger felt flimsy to me, even worse than Glock plastic. I hate Glocks because the stock is so angled that they are not comfortable to me to hold, and this gun was just like a Glock. But it felt even flimsier than a Glock.
Another girlfriend owned a 9MM Glock. Her little dog got a hold of it and carried it out from under her bed. She chased after him and grabbed it from his mouth, then put it in her nightstand. The next time she went to get it out of the nightstand, the spot where the dog carried it in his mouth had rusted, and it had 2 small scratches. Keep in mind that the dog had it in his mouth for maybe 10 seconds, but that was enough to make it rust. To me, that is not very good quality. I know plenty of people swear by them, but I cannot make myself like Glock.
The weapon I was issued at work is a S&W M&P .40 cal. I don't know that I would say it is a POS, but having fired it, I don't think I'll ever go and buy one for myself. I'll stick with Para Ordnance, H&K, Colt, and Beretta weapons.
