The Para I knew had a DA called LDA (Lightning DA). It was pretty slick for a smooth long trigger pull but the trigger bar looked very dodgy. The single stack series was known as the C7 and the compact officer size was known as the C7 companion when it debuted around 2003. Per my recollection, the slides were series 80 style and interchangable with Colt 80s, even the DAs.
While I actually used the C7 Companion in self defense, it was the Para that soured me for life on the brand, which was significant considering I was a huge fan of their 14.45 LDA I got around '01. They replaced the C7 twice and when #3 was a turd, George Wedge told me in so many words they had to make a business decision to lose my patronage rather than lose another dime making things right with replacement #3.
Problems included improper heat treating causing peening at the slide stop (causing the weapon to fail to lock back), mis-drilled slide stop, poorly finished and flaking MIM parts including a broken extractor, poorly welded mags in which the floorplate of a single stack mag ruptured from insertion sending a cascade of bullets everywhere. I also recall the tritium was exceptionally dull in the sites, but whether that was right or not, I am positive I am forgetting at least 2 other things.
Para went from innovative quality with customer service second to none (late 1990s-2002) to a sinking ship consisting of fugly gimmicky products, poor customer service and significantly cut corners on QC. I have little idea if they ever turned a corner during the 2010s but the sale to Remington's owners with Para-like Rems having shoddy quality and telltale signs like this forum having only 3 posts within the past year and posts on page 1 being older than 5 years suggests they are headed into their well deserved place into the abyss of gun business failures.
Avoid like the plague.
