I only own one Para, a P12-45. I bought it used at a gun show with the usual swearing that it shoots dead on and never hiccups - it shot six inches left at 10 yards and four inches high. It would not go three rounds without a jam.
I did some very minor work to it and now it shoots dead on and is 100 percent reliable. The work consisted of some cleaning, polishing and spring replacement.
As near as I've been able to ascertain the gun was made in 1994 and never detail stripped or had any springs replaced. It was kind of a no-brainer.
I've helped a couple folks with minor problems with Paras and all the fixes were possible to do in the field.
I read a lot of negative posts about certain guns, but for the most part I believe them to be unfounded. Most things people send guns back to the factory for can be fixed in minutes if you know how to diagnose the problem and can detail strip the gun.
It may take a few special tools, but not many. One of my most-used tools is a cheap pair of pliers with serrations ground off to bend mag feed lips. Remember, 90 percent of feed problems are mag problems. Almost all mag problems are spring, follower, feed lips or dirt related.
I would guess 90 percent of the people who have Para issues haven't cleaned their mags or followers in the last 200 rounds. Para mags should also be cleaned on the inside, not just wiped down on the outside. That is one of the key issues in keeping them feeding 100 percent.
