I would have no problem with pump guns like the 870, 1300, and 590. No experiance with the Nova. I could also put up with a Browning or 37 Ithica as last choices due to bottom ejection
I am a big fan of a pumpgun for home defense, especially if others of the family may need to use it. Same reasoning I use when recommending a revolver. It is simple to operate, and not prone to malfunctions.
I have had one semiautomatic a Beretta 1201FP. No issues with it either as long as you train with it.
My home defense shotgun is my old Scattergun Technologies TR870 Nashville Tenn. Pre Wilson Combat. It was built on a Wingmaster instead of a Police. It has the Speed Feed Stock set, Side Saddle, Scattergun Tech Track Loc sights, and originally had an Orange Hi Vis Follower, which I have since changed out for a Higher Visibility Green one. It has a Big Head Safety, sling point between the magazine tube, and tube extension, and also the clamp between the barrel and magazine tube extension. Not sure 20 years later what all Scattergun Tech might have done internally to it.
I carryed the TR870 for 15 years as a Deputy Sheriff, and 2 years as Police Chief. I have had Zero Malfunctions with it.
The wife and I also shoot Trap some. Again we have 870TB trap guns. I do not recall any malfunctions with either of them. If we ever did have a Trap Gun issue I am sure it was a relaoded shell issue, and not the gun. All 3 of our 870's are pre 1980 Wingmasters.
The local PD has older Model 870 Police shotguns. They were getting a little beat up looking, and were getting ready to upgrade to something newer. I suggested they have them refurbished with new Speed Feed Stock sets, and have our local gunsmith parkerize them. That was probably 10 years ago, and they are still happy with them. I have never seen one of them fail to function in training/qualification either.
