NDZPerformance.com Reviews 

I ordered a barrel and then I read these reviews and got nervous, thinking id have trouble getting it, so I emailed to ask if I could cancel. The guy got right back to me and was nice and immediately refunded my money. I had it back in my account in 3 days. I was thinking it would be a nightmare, but now I wish I would have just got the barrel. Maybe they made some improvements

Would give a -5 Stars if I could. Mike from NDZ is an Absolute Clown with an Attitude. I was a loyal NDZ Customer for some time and spent a lot of my hard earned cash with this Business. Everything was good until they screwed up my (VERY LAST) order and I had to contact "Customer Service" I sent them an email with the photos below explaining that I was missing a part in my order. I never received a response so I called about my issue and was told it was being taken care of. 12 days later I called again since they never bothered to answer any of my many follow up emails or contact me about the status of my missing part. Mike answers the phone and gives me a very nasty attitude saying he replies to every single email and I never sent him anything. I told him to give me another email address and I will forward him all of the emails I sent. He was getting furious with me and screamed the email address to me in a raging voice like he was going to lose his mind. It seems like "Miserable Mike" as we will call him hates his life and his job . He is Very Very UNPROFESSIONAL !!!!!!!!!! In the end of all of this Mayhem he doesn't send me the part I was missing and refunds only half of the money I paid for the part. I asked him what happened with the part I ordered and he told me it doesn't matter you have been refunded. Really ???? Why the hell did I bother ordering a part if I never received it and only received a partial refund. I will be Disputing the charges with PayPal and NDZ will NEVER EVER get ONE RED CENT FROM ME EVER AGAIN

Placed two separate orders first order was a guide rod kit worked perfectly although I went too light, my second order went big with grabbed several parts and I gotta say I’m very happy ndz hasn’t failed once this is my go to shop for now on!!!

Defective item. Horrible customer service. Give your money to a better company

Was having trouble breaking down my S&W SD9VE. Installed NDZ Extended slide lock lever, super easy to breakdown now. Yessss

Ordered Glock Gen 3 compatible trigger (complete) for what looked like a good price. Picture on the NDZ website clearly showed a completely assembled trigger. Purchased the item and received it in an acceptable timeframe. However when the package was opened three separate packages containing the parts for a trigger were found. What wasn't found was the trigger spring. Contacted customer service and asked that they send a trigger spring and all would be good (was able to use and old spring as a backup to install what I had purchased). They responded that the spring was not included with this item. Sent a screen print from their website showing a complete trigger assembly and asked again for another spring to be sent to me. CS replied to me with a screen shot showing at the very bottom of the page, a statement that the trigger spring was not included. Guess I should just chalk this up to stupid tax but not happy with the false advertising practices of showing a fully assembled trigger to lure you in.

I placed an order for a slide kit with firing pin and waited almost a week for the order and received a magazine extension for a gun I don't even own. I tried contacting NDZ through their number and constantly get a voicemail message and their email support is horrible. I honestly regret buying from this company, it has been a total waste of my time. Be advised, don't purchase from these folks until they get things figured out in terms of customer service. Horrible company!
