I really like the concept, but I took another route. It's cheaper route, so it's really just me being me again.
I like the bolt action, in general, for its inherent accuracy potential.
But I like semi's and chose the Ruger 9mm PC Carbine. It' not a lightweight, and I'm actually counting on that as a plus. It seems to absorb recoil (yes, it's negligible anyway), but it seems to stay right on target throughout the recoil cycle, and I'm having trouble trying to find something wrong with that. Followup shots are very simple.
Right now it's set up with a simple small diameter reflex sight that allows for four different reticle patterns and displays in red or green. It's only been shot out to 100yd so far. It's capable of accuracy at that distance that's considerably better than I can manage with a Ruger American 9 Pro. There's point here, and it's that my two firearms, the 9 Pro and the PC Carbine, can use the same 17 rd mags. But If you like, there are two other mag well adapters, including one for Glock; and that can accommodate 30 rounders. I'm tempted to replace the optic with reflex utilizing variable magnification, because I think that with better optical resolution, I can get it to shoot smaller out there.
But I also believe in limits, and going beyond 100yd with a minor power factor cartridge seems a bit much. To each their own. If I want to have greater range available, I can easily substitute my M4gery.
Meanwhile that cat eliminator is one peach of a firearm, and I commend it, its builder, and the manufacturer who picked up on the concept. This from a supporter of four cats (no one actually owns a a cat....).
