My friend just got a Para Ordnance today, and it was the finest thing. But there were a few things about it that we don't understand. 1.) It had what looked like a match grip, with a wide base, but he never saw anything like it anywhere else. 2.) It had a much more prominent mag release. 3.) Instead of having a recoil spring plug that would screw off, it had a long rod with an alan wrench dip on the end. We think this may be a special match/target model, but haven't found any info on it. Anyone know what's distinctive about its features and maintenance?
