It was the "cool compact semi-auto" to buy back in the early-to-mid-80's (and I did) just before divorce-induced poverty closed the books on my gun collecting hobby for 25 years. I never got to shoot the damn thing... and in the meantime, plastic came along and replaced heavy stainless steel. The Back-Up .380 suddenly became a curiosity and relic of a time gone by.
I've still got it in the back of the safe, box and all. One of the original magazines had a plastic part that literally disintegrated over time, but fortunately, I was able to replace that part. In fact, I picked up a couple spare mags for it while I was at it before they disappeared entirely.
It amazes me that these odd little relics still sell on GB for as much as $250.
I'm just waiting for a good local moonbat gun buy-back so I can dump mine and use the cash to buy something good.
