If a 1911 can't reliably handle 100 rounds of factory ammo, including some fast shooting, there is a problem. And there are some problem guns out there. I've owned one or two.
Gun matches run the gun hard and can reveal reliability problems with a gun. They can also expose ergonomics and other problems with the guns that may not be apparent at regular shooting sessions. Shooting competition puts you under some pressure to shoot so that your marksmanship and manipulation skills have to be honed. But you don't need 3 gun to train, and certainly not to be able to defend yourself. There are also other ways of running the gun hard on the shooting range.
I would want to do some realistic drills on my own with any gun that I might use for home defense--and not just fire a few rounds offhand and call it good. You want to start each drill with the gun in low ready with the safety on.
For example, fire one magazine worth of ammo where you bring the gun up from low ready while disengaging the safety and firing one shot. Then engage the safety and bring the gun back to low ready and repeat again until you have expended the rounds of one 20 round Ruger mini-14 magazine. Then fire one magazine's worth of bringing the gun up, disengaging the safety and firing two shots. Then safety on and back to low ready. Then do a magazine's worth of failure drills where you fire two shots to the body and one to the head. Then do three magazines worth of non standard responses--meaning bring the gun up from low ready, while disengaging the safety and then fire from 3-6 rounds as fast as you can accurately get hits. You vary the number of shots you fire each time you bring the gun up from 3-5, hence the name non-standard response:
https://pistol-forum.com/showthread....nsive-shooting Try to integrate multiple target drills where you have to fire rounds at one target and then fire them at a second target. This can even be two bulls on one target at close range if that is all you can do. You want to shoot those drills as fast as you can while getting accurate hits.
We are comparing it because Glenn included a Mini-14 in his study and concluded that it would look better in court. If we are talking about some place a standard AR is legal I would much prefer an AR over the Mini-14 for reasons of reliability, durability, better ergonomics, easier to mount things like a red dot sight which is a game changer over iron sights.
Question: are you restricted from owning and using a 20 round magazine for your mini, or does it restrict the sale of new magazines?
