I do not and will not own any inertia OR recoil operated gun. I have, but no more. The inertia action
requires the receiver to move rapidly to the rear in order to compress the back of the bolt and throw the whole bolt to the rear. They kick like a mule unless equipped with two piece stocks and such. Yes, they are simple, they do work
with the right loads, and they will go a long way between cleanings. A certain manufacturer has done a magnificient job building a cultural mystique around their guns, and charges premium prices for a simple action to produce, and is now outsourcing parts to a less than usually highly respected area of the world. Since the original patents have expired, more manufacturers are jumping on the inertia bandwagon.
I now own nothing but gas autoloaders. They are available from a number of good manufacturers in numerous gas system designs. They spread the recoil pulse over a longer time by the nature of their action, and they are available in any weight range to suit your fancy. They do need cleaning, but the situation is not nearly as dire as the non gas lovers would have you believe. They are available that will shoot anything from mouse fart loads to 3-1/2" Roman candles interchangeably, hence the same gun can and oftentimes is used to shoot clays and everything else. I am primarily a waterfowler, but I usually shave and have a real paddle, so I don't find the need to own an "inertia driven" gun.
In truth, either action works, I just don't like one. I'm not a real lover of the I-talian guns with either action.
