Hi all. I'm a boot here so bear with me. Bought a G43. After 100 rounds, cleaned it and sent the frame out to be painted. Weapon operated fine, mags dropped ect.The frame was assembled when I mailed it out. When it came back the mags do not drop freely. Hit the mag release, the mag clicks loose but you have to pull the mag out. It's not difficult but we all know there's an issue. I bought a Vickers Tactical extended mag release and it's real tight going in so I didn't keep it in the frame.Did the frame shrink? I won't get into the company that did the work I am currently seeking action. My question is: what if anything, can I do to get my mags to drop? The weapon fires and fuctions. The magwell has cerakote but it doesn't appear to be thick. The frame does look good but obviously I can't carry it as a new backup duty gun. Sandpaper? Wool? Never had a pistol painted and I bought my 1st (of many) Glock in '99. The guy who did is arrogant and states he did nothing wrong. Thank you! Stay safe!
