43x frame
43x frame doesn't fit 15 round oem Glock mags they are to tight and when I emailed the manufacturer they basically said they know the issue and that's it so pretty terrible follow up I only bought this product to increase ammo capacity so it's basically pointless at this point

Order cancelled
You cancelled my order because the FFL didn’t respond. No one contacted me about this until it was cancelled. I learned about it upon inquiry and offering to contact the FFL. Very poor communication on your part. I will shop elsewhere in the future. I placed an order with a competitor and received the product timely.

Issues
As far as looks i would give this frame 5 stars. As far as functionality 1 star. It has not fired but one round then the magazine falls out. The Brownells slide worked flawlessly with the glock 43x oem fame. But the minute i put the SCT 43 frame on with it there were issues. Chamber a round fire and mag falls out. Reinstall chamber a round magazine falls out. I thought it might be a stock oem magazine bad. I bought a new magazine and the same thing happened. Installed the oem slide on the sct frame and the same thing, magazine falls out aft the first round. Inspection of the magazines ive used you can see where it appears to be the slide hitting the back right corner leaving marks on the polymer. Not sure if its a tolerance issue with the sct frame and Brownells slide or what since the Brownells slide works perfectly with the oem glock 43x frame.

Glock lower
My Glock 43x started malfunctioning after placing this lower on the gun. The rounds would not cycle properly so I put the original back on the gun with no issues afterwards.

Poor
It is fine IF you like box stock glock but these SCT frames will not function with Apex triggers or any after market parts. You are stuck with stock glock or sct parts only. Great ergonomics, much better than stock but the con of stock parts makes it a no go. Poor design

Failure to feed
I’m having on average at least 2 failure to feeds with Federal Punch and Hornady Critical Defense 9mm rounds. I’m using a nickel plated S15 magazine in a complete SCT lower and a complete Zaffiri upper. My actual G43x MOS lower doesn’t have any failures. Looks great. Feels great. It needs to function properly.

Dead Trigger Issues (Many YT videos on this topic)
Used 2 different slides with same issue. Dead trigger after 1 or 2 rounds and totally unreliable. After searching YT and Reddit, many with the same issue. I refuse to start bending bars and tampering with safety mechanisms. Get it right or don't sell it folks! I questions that these are all Glock OEM internals. Cannot recommend until they fix this issue.
