I'm flattered you guys think so.
The specific answer here is that without testing your specific gun with the specific ammo in question that way, you won't know for sure.
The trainer's answer here would be that what is commonly referred to as "hip shooting" with a firearm isn't really a useful methodology. Whether discussing a pistol or a long gun, use of the gun "from the hip" doesn't allow visual verification of where, exactly, the projectile(s) are going. Under ideal range conditions where the shooter and target are static, the distance is known, and the shooter can pick his moment it is possible to make hits.

...has proven ineffectual at teaching a typical person how to prevail in a gunfight. From a teaching perspective, we don't want people trying to use shotguns like that. The various "shockwave" style guns on the market are a terrible idea as a defensive tool that can really only be made useful for the typical person by adding something like a laser on them. Even in my hands, a "shockwave" takes twice as long to get on target and use as a properly stocked shotgun used from the shoulder.
If we are talking close quarters use of a shotgun, short stocking is usually a superior method and when used with the proper technique isn't any more or less reliable than use of the gun on the shoulder.
If we are talking about diminished capacity use of the gun a la Special Agent Mireles in the Miami fight, attempting use from the hip is going to be less effective than getting whatever shoulder still works behind the gun.
The inertia recoil system depends on a difference in movement between the bolt assembly and the whole gun. From a purely functional perspective, the inertia guns have a happy zone where they function reliably. That happy zone depends on a certain amount of recoil taking place to allow the mechanism to work properly. This means that someone like Rob Haught finds inertia-based semi-autos useless because his recoil mitigation is so powerful that he actually chokes the gun by not letting it move enough to operate. I don't find many people who have the same problem because they aren't as strong or skilled at the technique as Rob Haught.
Conversely, if you allow the whole gun to move too much, it will rob the bolt of the energy needed to complete the ejection and feeding cycle.
If I had to venture an educated guess, I'd say that trying to run an inertia based gun "from the hip" with low recoil ammunition is a good way to induce stoppages. My recommendation would be to eschew using the gun "from the hip" because it's generally a poor methodology for effective use of the gun.
If you depend on the gun for self defense, it is a good idea to explore function with low recoil shells and what conditions are required to make it run reliably...but I'd consider it's ability to function in "hip shooting" to be ranked somewhere below whether or not I like the color in terms of importance to me. YMMV.
