My MX20 pictured here is kind of a hybrid "UK style" with a sporting/game style buttstock and a game forend. I haven't seen Daryl's MX20 except for that one pic, and so its best for him to reply. On the other hand my new MX8 in 12-gauge is a competition gun with an adjustable comb, palm swell and beefier buttstock. But it has the game style forend which I wanted. Also the adjustable comb so I can shoot sporting as usual and quickly move/from Trap when I occasionally shoot it. Besides personal dimensions, many options for wood configuration and barrel length/weight are available. Also increasing levels of better wood figure. And then you have the different frame sizes with drop out or fixed trigger, selectable or not, and coil or leaf hammer springs. Really, every P gun is made to order and it's fair to say that no two of them are exactly the same. I understand the factory currently makes only about 1600 guns/year. Perazzis are noted for superb barrel and choke regulation, weight balance, swing dynamics and reliability; and with a modicum of care it's common for guns to run 100,000+ rounds before a tiny oversize locking block might be needed. A common saying amongst P gun shooters is "do you want to drive a Ferrari or a Tiger tank, or a log truck" .... or other similar comparisons? Not my saying, just posting what I've heard from higher class level sporting clays shooters many times.
Craig, that Perazzi in the link you posted looks and sounds good except that I'd prefer a selectable trigger and I don't like checkered butts. Just my personal preferences.
