I got a Shield Plus late last year and like it a lot. Mine has roughly 500 trouble-free rounds so far. I’ve never shot a Shield 1.0 or 2.0, so I can’t compare. I’ve shot my friend’s Sig 365, though, and while I liked it, I like the Shield Plus a little more. Even so, I wouldn’t hesitate to buy a 365, or at least a 365XL.
Prior to this, I carried a fullsize 1911 and a S&W 3913. So the Shield Plus feels tiny and very lightweight in comparison to those two.
While I shoot my 1911 better than I do the Shield Plus, I shoot the Shield Plus better than I do the 3913. Of course, all three have completely different triggers. I love the 1911 trigger the most out of the three, but the Shield Plus trigger is fantastic for being a striker-fired trigger. I like it slightly better than my friend’s P365 trigger, which I also found to be a pretty good trigger. And I like it much better than my Glock 34’s trigger.
As for ammo, I prefer 147 gr for my Shield Plus. I’m still trying out different brands and varieties of ammo, though, but of the ones I’ve tried, they’ve all cycled reliably so far.
At first, mags were hard to find, but they’re now much more available. The 13-rounders were hard to top off at first, but the more I loaded and shot them, the easier they got to top off. I read on another forum, though, of a few who’ve had the bottom plastic spacer cracking on the 13-rounders when releasing the mag and having it drop and hit a hard floor. So that’s something to consider.
I’ve also read on other forums of the little slide lock spring popping out of its place and preventing the slide from properly cycling. The few who reported it have had difficulty popping it back in place in order to remove the slide and replace it. From what I’ve read, it’s an uncommon issue that also plagued a few of the earlier 1.0 and 2.0 Shields. Luckily, I’ve not experienced any issues at all with mine, and I’m guessing this particular problem is few and far between.
