    Glock 43 80% frames

    I currently have a G43x. Iíve fantasied having my cake and eating it too by way of having both a 43x and a 43 frame that will both run the same upper that I could swap in a pinch (the latter frame being for ultra-concealability). My questions are...
    • Will a 43x slide run on a 43 frame, with 43 mags?
    • A google search has turned more than a few polymer-80 G43-type frames. Which one(s) are most reputable?
    • Do polymer-80 builds open up a can of worms legally if at all used in self-defense?

    80% frames are completely legal, but different states have different laws around them. But normally the 80% frames cost as much or if not more than a complete one. Online I'm seeing G43 frames that are complete as low as $99, I will put a link below. I've also been wondering about compatibility too. I have not found anything either way but will be watching this thread as I have a G43 and may want to purchase a G43x lower and go in the opposite direction as you.

    Actually, just browsing that site there, I think I have found an answer for you. The following may help. Looking at compatibility specs on this upper, it fits a G43, G43x and G48. If the upper is compatible and can fit 3 models, I should think the G43 lower should fit the upper from your G43x.

    I hadn't thought about doing this, but I'd love to buy a 43x/48 lower for my 43. Too bad they are out of stock.

    My mind is going back and forth between magazine extenders and a new frame... It's a shame the magazine from the 43x does not fit in the 43.

    I already have +2 extensions on my 43 mags. Getting a new gun for 2 more rounds was holding me back, but with the Shield Arms mags it adds seven more rounds. That increase has me wanting the 43X or 48.

    Plus I just sold my 19 to my brother since it was the only way I could get that cheap bastard into a decent gun. I feel weird without it and want to replace it. I may just get a 48 (if I cna find one) and be done with it. Changing the frame on my 43 would be a cheaper way to get into the Shield Arms mags, though.

    Those Shield Arms mags look interesting, I was unaware of them before now. It makes the G43x more interesting, especially when compared with the 26 or 19.

    I own 4 of them, they are good to go. But right now they are extremely hard to get because anytime Shield Arms posts new stock they are sold out in hours. You have to treat getting them like an eBay snipe.

    Edit: I see you're in Fort Wayne. Sportsmans Warehouse has them in stock online. If you are at all inclined at getting a 43x or 48 you should pick up some mags. If you don't to get the pistol later, those mags will be an easy sell.

    Supposedly the other reason they are hard to get right now is that Checkmate just moved their manufacturing out of New York to Georgia causing a gap in production while they move machinery.
