It seems it's generally be a bit difficult to find a consensus on the Para pistols.
The most recent experience I can think of is when a fellow brought a used (LNIB) P-12 compact he had just bought to the range. He didn't make it through a box of ammunition before experiencing some instances of premature slide lock (slide stop lever not fully engaged in the slide notch, unlike when it's actually activated by the follower), nose-dive feeding down into the magazine (not even reaching the feed ramp) and one of the rear sight paint dots flying off.
The causes might involve some relatively simple corrections and repairs, but I'm not sure the fellow intends to keep the gun after his first range experience with it.
I remember attending an armorers class one time where the subject of Para pistols came up. The instructor showed us a sear he'd previously received and which came out of a Para pistol earlier. It was severely bent, almost folded upon itself in the direction of the normal curve. Seemingly a 'soft' part.
I know a fellow who is a vendor in the firearms parts business. He used to shoot a Para LDA in weekend competitions, along with a friend of his who also had a LDA. Neither of them were satisfied with the functioning of the pistols, and after a trip or two back to the factory for correction they both decided to try something else. My friend tried a Springfield which worked out well for him.
Now, you can hear this sort of thing about many different makes/models/calibers of pistols, and anecdotal examples can vary as widely as the folks relating them.
Also, satisfied owners/users of just about any make & model of pistol are most likely going to be disinterested in hearing about the unsatisfactory experiences of some folks ... not when their own guns are working well.
Trying a rental gun at a range which offers rental service can sometimes be useful, especially if you invest the money to run a few boxes of different ammunition through one which potentially interests you. How about attending a local IDPA match and at least observing the experiences of any Para owners, and perhaps talking to them afterwards?
I've never felt interested in spending my own money on one, myself, but that's just me.
Double column .45 magazines can sometimes come with their own headaches.
