I'm really happy to hear that everyone has had flawless results with the Magguts +2 for the shield. I just recently got a shield and didn't expect to like it so much... other single stacks just didn't quite cut it for me as far as size to capacity ratio, but the shield seems to be sufficient from the factory, and with +2 for only an extra 1/4", you simply can't beat it. Really makes me wish that all the single stacks had a 1.5 stack magazine like the shield, such as the Walther PPS M2(which I just ordered because i couldn't resist the $100 rebate, ending up being $257 net price in the end), and I'll probably get the magguts +1 for the PPS M2, but that only brings it up to 7 rounds... but it is shorter in height than the shield. Either way I think I'll probably end up sticking with the shield as nothing else is going to be able to touch a shield with only 1/4" added to the height for a 9+1 capacity.
When you guys test your guns with the magguts, do you load a full magazine plus one in the chamber? In my experience with testing handguns, the one case where I seem to be most likely to encounter a malfunction is with a fully loaded magazine plus one in the chamber... in fact when I first got my shield, the very first shot was a failure to eject (stovepipe) because I loaded a full magazine plus one in the chamber... I guess the magazine was just so stiff that it slowed down the slide too much to successfully eject the spent case. It actually happened twice in a row (not the next round in the mag, but the same situation; full mag plus one. It hasn't happened since, as I left my mags loaded for a few days before going to the range a second time, and I am confident that I can keep it loaded like this and not have any more issues. My friend's PPS M2 did the same thing when I shot it, and the only time Sig P320 subcompact malfunctioned was one time when I had a full mag plus one. It would definitely be a shame for you to not be able to count on max capacity in a single stack.
