I don’t have the Performance model, so I can’t speak on that. But I do have the regular Shield Plus with the 3.1” barrel and love it. The trigger is fantastic, and I shoot it just as well as my 1911 from 5 to 15 yards. Someone mentioned “softer” shooting, and I have to agree. I think what they meant is that despite its size and lighter weight, it’s not snappy in the hands and recoil is manageable, which really surprised me. I haven’t shot the other subcompacts, like the Glock 43, Hellcat, P365, etc., so I can’t compare how those feel in the hand. But I have shot a relatively light, snub-nosed .38, and I did not enjoy shooting it. It was really snappy, meaning it feels like someone punching your open palm, not really hard but hard enough where it’s a bit uncomfortable - not painful just uncomfortable. That’s not the case at all with my Shield Plus. I don’t know how S&W did it, but for me, at least, there’s no snappiness and surprisingly manageable recoil.
Being smaller and lighter, it obviously conceals better than my 1911 when carrying concealed. I’m 6’ but lean at 165 lbs and can conceal either one with a large, untucked shirt strongside. But the weight difference is more noticeable between my Shield Plus and 1911. For my 1911, I need a much thicker, more expensive dedicated gun belt to carry OWB. Otherwise, the weight of the gun (no matter the holster used), tends to cause the holstered gun to bow out a bit from the grip and requires cinching the belt down uncomfortably tight to keep my pants from sagging down. That’s not an issue with the much lighter Shield Plus when wearing a thinner, synthetic gun belt OWB. As an aside, it’s also not an issue when wearing the heavier 1911 IWB - only OWB.
Just thought I’d share my experience with the Shield Plus. Hopefully it helps you decide if you want it or not.
