That is easy. Many moons ago I had saved up spare cash to buy a nice gun. I was between a Springfield TRP Operator or a Zenith MP5 clone. After reading a VERY generous review from TTAG about Roberts Defense I figured it would be a good option. Solid guns, hand fit, made in US, super accurate, ate everything, and you got a superb gun that cost way less than it’s worth. Couldn’t find a bad word about them anywhere, seemed like a good bet.
So I ordered one, super excited about it, felt great… couldn’t get through a single mag without a FTF or a three point failure even. Tried bunch of different mags: ACT, Colt, WC, CMC, etc. Same with ammo of course and no combo worked.
I sent it back to them for repair, but because I didn’t buy it from them directly I had to eat shipping cost. They sent it back saying they tuned it and ran through a box of JHPs and FMJs without issue. Me though? Same problem, couldn’t get through a single magazine without a malfunction.
Ended up selling at a huge loss. I think it cost me $1,600 or so initially, another $100 to send it back, sold for like $900.
That was the worst to me since at the time I had never bought a gun more than $800. I spent twice that and then some and also took my biggest hit in a sale or trade too. I was also mid 20’s and I made decent money but $1,600 was also a whole lot to me then.
