DudeBro:
You can swap the sights - they're dovetailed, which makes it pretty easy, and if Para stayed with their own standards, it'd be an inexpensive upgrade. Forget about the ramped barrel and PXT, though. Just not worth the effort. Para sells a 7.45 in the $600 range that's got all the good stuff (everything but an arched MSH, which is one of my "musts"). The price difference is small enough to justify going that route unless you're
really up against it. Looks like:

I installed the arched MSH and frontstrap finger grooves. The rest is "stock". This gun's really blue, too! My camera decided to muck with the "white balance" and grey it out a little.
Hawk:
I'm not sure about this gun, but all of my Paras are equipped with the chamber slit. I expect they're doing it here, too, although there's no reason (other than the lawyers) to do so. AFAIK, putting a mag safety into the 1911 may not be easy. I think you could do it to an LDA (the rules are already bent beyond recognition :)), but an SA is another animal.
