Good selection, fast shipping and quality products.

Very quick shipping, great product!

item fit was very good looks great

They made it in faster than I expected

Great product. Reasonable shipping time.

I also purchased an extractor which installed with no issues. Still having some extraction issues. May be due to break in time, limp wristing or some other non oem parts in my Sct frame oem Glock 43x build. Only got about 50 rounds thru it. Barrel and recoil spring are non oem and Sct frame are not Glock oem. Not sure this makes a difference or not. ?????

The parts are of great quality and their costumer service is top notch. I'm a returning costumer and as long as they keep doing the great parts they got me for ever

Great site easy to navigate all around nice experience

Works just fine better than I expected

Stainless Steel P365xl threaded barrel was perfect. Put the barrel in, weapon looks great. Will be adding more upgrades.

product availability, web sight Was good. shipping was quick!

The company is easy to work with and got my product in a timely manner

Received product very fast!

👍🏽

The springs are very smooth took a good bit of the snappness out of it.

They were fast to respond and hopefully they will swap them out for stock weight springs

NDZ has superior quality products. Extremely patient, friendly, and very knowledgeable and efficient Customer Service technicians! And interesting design features in their "upgrade" products!

The guide rod fits perfectly and functioned flawlessly at the range. Tamed the recoil on 10mm full power loads out of my Glock 20.

Easy to order. Received product in a timely manner
