Can you take out the 9mm barrel an mags on the Shield Plus, an put in a 30 super Carry Barrel an mags an convert it..
Or is there some other things that would need to be done..?
No. 30SC is a narrower case, so it requires a different breach face. Yout need a 30SC slide, barrel, and mags to convert.
Heck, once you go that far, you probably wouldn't be too far off from just buying a new 30 SC model. They've been going for as low as $300 lately.
What can or have you done to the Shield Plus?
I upgraded the trigger to an overwatch precision and put a Holosun 507k on it. Love shooting mine got over 2.5k rounds through it.
I don’t know why… I totally forgot about Overwatch.
At the time, I had the Steel competitor when it just hit the shelves a year or two back.
Overwatch was the only company that had anything for it, way before Apex… I went with their kit and it was amazing…
I totally forgot about that until I saw that red safety blade..
I may just think about their kit for my Shield Plus… I liked it that much.
I bought mine from a online reseller and it was like $50 off list price "clearance" so at $100 plus the gunsmith cost it was worth every penny.
M'Carbo has a spring kit which I bought but ultimately just went with the overwatch kit.
Put Holosun K series dot optic on it.
Bought a stripped 4" slide for it, then all the parts to build up the slide and put a K series on it and it still rides like that.
Liked it so much I figured I needed a spare/back up for it so now I have two of them. Same 4" slide and same parts to build it up but it sits on a .30 SC frame.
I converted two Shield Plus mags. to .40 S&W and bought a .40 S&W slide/barrel for a Shield. Works great. Only problem is the .40/9MM geometry doesn't work as well in the Shield Plus magazine as it does in the full sized gun magazines. There's not a -2 round penalty for .40 vs. the 9MM. It's more because the magazine is thinner to start with. I can only get 11 rounds of .40 in a converted 15 round Shield Plus magazine. Only took it to the range a couple times. Need to convert two or three more magazines.
And, the holes aren't in the right spot to count rounds with .40 vs. 9MM.

The Shield Plus frame with the .40 S&W top end on it. If it keeps working well I'll be getting the slide milled for a 407K, or an EPS carry (same foot print.) Sorry, this is the other one. A Shield .40 slide with a threaded .357 SIG barrel and compensator. My wife says she can tell the difference between this one and a 9MM but it's not bad at all when shooting it.

Really, an 11+1 .357 SIG or .40 in a package as small as the Shield Plus isn't a bad thing.
What did you do today modify the magazines? And what. 357sig barrel are you using? I have a pc shield 40, and would love the extra capacity and the newer factory trigger. Knowing that this is doable makes me a very happy camper. Does it run reliably with the .40/.357sig?
