I believe the main problem with the Paradigm was the unreliability of supply, and the fact that the maker kept changing the specifications from those originally supplied to and accepted by Webley.
Before Webley as was went tits up, I was hoping to get a look at a Paradigm, as my friend at Webley was due to collect three examples from the maker in Dorset, and was going to call in to me on the way back to Brum, but, yet again, he got a call saying they were not ready so I never did get to see one.
I believe several, I think it was three, did eventually find their way into Webley's hands, but had to be returned to the maker on the demise of Webley as was.
I did hear, I think it may have been on the BBS, that the maker was going to try and get a Chinese manufacturer interested in their manufacture, but I haven't heard any more about it.
