A while ago there was a thread asking about the reliability of the +1 magazine spring kits from Magguts and I was pretty insistent that my experience was good. And it still is, for the 6 round magazine kit ONLY.
I haven't tried the 7, but the 8 is a total fail for me. The first kit did not work, so they promptly exchanged it -- good customer service! -- and the second kit did the same thing. I installed it into a brand new extra 8 round magazine and it did exactly the same thing.
Here's the gist -- the metal follower they provide is able to tip forward/downward under the nose of the bullet in a way that the factory follower doesn't. And if the top round "noses down" in this way, the rest below it do too, and the follower gets stuck at the very bottom of the magazine. Stripping off that top cartridge leaves the rest of the rounds rattling around loose inside the magazine. A good smack to the bottom of the magazine will release the spring and reseat the rounds properly, except for the one time it clearly didn't when I was firing it. That resulted in a misfeed.
It only happens when the magazine is loaded to capacity with 9 rounds. But the "nosing down" issue can arise on its own when carrying the gun with a round in the chamber. I first discovered this when I went to the range and dropped out the magazine to switch out my hollow points. I can only presume that if I'd tried to fire in that state, I'd have had another misfeed.
Anyways, two different spring kits in two different magazines, exactly the same problem in both. Magguts will refund me and says they cannot replicate the problem, but it's at least clear to me that I will not be using their kits in my extended magazines.
(since discovering this, I've tried everything I could to force the+1 6 round spring kit to have the same problem, and I can't. So I still consider that one reliable).
This video should illustrate the problem. I sent the video to Magguts.
