I've own a Para C7.45 Companion.....
for the last two years and it has been reliable and accurate for me. It has fed any kind of ammo I shot through it.
I had a challenge at first with the Para mag, switched to Wilson's and that prob disappeared. Had to change the recoil spring once, put some skateboardtape on the front strap. Is a champ!
But I prefer C&L and lighter guns for CCW...the Para is heavy. I bought it for work as I was mandated to carry a DAO or DA w/decocker then. The Para gave me the same feel as my long carried Officer's model and used the same mags.......so it is what I got.
Now I carry what I want on duty......and it is a Colt CCO for me.
The LDA may be a silly design for some, but it meets certain criteria for the admin type that tell folks what they can carry in their holster. And if you have to have a DAO...the Para has one sweet trigger pull, coupled with excellant accuracy(the ones I have tried).
But given the choice, I'll stick with single stack(better reliability) mags, Single action(less parts to mess up at the wrong time), and a longer slide/barrel combo of at least 4 inches.
I have personally never had a problem with the 3.5 inch Officer's(had three, not counting the Para), but apparently such problems do surface. Since the hard part to conceal IWB is the grip, I do like the Officer's frame..but the slide is no big deal snce it is not visible.
I'll keep my Para, incase I need to have a DAO .45, and it makes a nice addition to the collection; but while allowed to carry what I want, the Colt CCO wlll be on my hip, on duty and off!
