Don't all Shields take same holster? I think they do but am not positive. I have several different holsters for my Shields, they say the Shield Plus fits same as regular Shield. One leather holster does but a plastic one not so well. I have modified it a bit and it seems to work OK with the Plus.
I carry my EZ mostly these days tho as I just don't have the hand strength to function the slide on the others. Whenever I get a roundtuit I'm gonna pick up an Equalizer which is the EZ with double stack mag, also supposed to fit the EZ holsters I have.
I think Lloyd has a .45acp Shield so he would be the one to ask about the holsters to be sure.
