Just some info for anyone curious: you can sand the polymer off one side of a G19 mag and it will reliably function in a G43X/48. Remove it from the right side if you’re right handed. Remove it from the left side if you’re a left handed shooter so that the mag catch works.
I roll with my 43X MOS with a 507 K co-witnessed with some Night Fision Costa sights, Talon Grip Pros, a TLR 7 Sub, with a Pure Tungsten Guide Rod from the GlockStore. She is my main carry, but sometimes I run my 48MOS into the mix as well. Same set up as my 43X only I removed the 507 K and use some XS F8 sights.
0:50 📝 With metal shield mags, should use metal shield mag catch/release. Metal catch on plastic mags or plastic catch on metal mags will wear the plastic out and CAUSE reliability issues!
G48 mos was my first purchase. After 1250+ rounds I’m now realizing I want a full size instead, looking at the walther pdp 5” going to be renting it soon, very excited.
Sorry, that makes no sense to carry an oem and a Shield for reliability. You either trust it or you don't. If you don't, don't carry it. I carry Shield magazines and have no issue. Have 4 of them. You should only carry oem if you don't trust it.
