Fabbri lock design has been constantly evolving and now is effectively a trigger plate lock. the sideplates are access covers. Proper sidelocks are an anachronism and have been for some time. Functionally there is no longer (was there ever?) any advantage to the design, it has merely hung on thru inertia. The A10, or whatever it is from ConnArms, is as modern a true sidelock as anybody needs at a fairly reasonable price. It will be just way past easy to beat CA as a package in the marketplace. Good luck on that. Current Beretta sidelocks are pretty cool too for a pile more money. Older ones back to the '50's are marginally different but still at a level that doesn't need "fixing". And there are of course a buncha gunmakers that still will fill that need for the appropriate money.
The most demanding community in terms of both function and durability, international competition, has seen in the last few years coil springs finally being accepted. Of course Perazzi has been a good part of that with their coil spring drop outs, tho the trigger plate guns have been in there too. Life in modern times, eh?
But if you think the world needs a "better" sidelock and you can build it - I say go for it.
And best of luck
