I got to shoot a squeeze cocker, it was a very technologically advanced pistol. It had a gas delay blow back system, gas pressure kept the slide in battery, once the gas pressure dropped, the slide opened up. You can see pictures of the gas system here:

But, it had a problem. You were supposed to squeeze the grip than pull the trigger. The forward grip was a safety, or supposed to be a safety. However, if you were confused, you pulled the trigger, nothing happened. If you pulled the trigger and then squeezed the grip, it fired. I am certain an number of accidental discharges happened because someone pulled the trigger, realized that they did something wrong, and without releasing the trigger, squeezed the grip.
I got to handle the Colt 2000 back in the day. It was way too early for that type of gun, it was a DAO pistol, in an era when everything had a hammer. When I played with it, I thought, what a horrible trigger, no one will want it. Well fast forward 20 years, and semi auto's with hammers are being phased out in preference to DAO types.
Anyone remember the Randall M1911? The History of the Randall :
https://www.sightm1911.com/lib/history/randall_history.htm When it arrived, you would have thought, based on the print press writers, that the Second Coming of Christ had happened. I guess I am now living the Tribulation: Randall only lasted two years. The only ones I have seen were at gun shows. And they were over priced.
That and the Bren Ten. Never seen one of them, but if I had a box of magazines, I would have been a very rich man. they were going for $200.00 each, the object lesson is, don't buy a semi auto that does not have its own magazine. The company shipped pistols without magazines and then went broke.
