Maritime Spring cups made the firing pin assembly smoother than the stock cups. You asked, I’m just telling you my experience.

Good shipping and handling time, had the color of parts I wanted when nobody else did

Easy to find and quick to deliver! Thanks again!

Love NDZ, can't go wrong shopping for your upgrades here. Some of the best prices as well.

The parts are great and they'll look amazing once I find someone to put them on the gun.

I love you guys. Everything I’ve purchased from you has been amazing. I just wish you’d throw some coupons around once in awhile. I appreciate the free shipping over $60, but to get a 10-15-20% off coupon occasionally would make me pull the trigger when I’m second guessing the purchase. Some people, like me, can’t afford to make one big purchase. I have to break it up every so often and make more smaller purchases. Things here and there. To be able to use a coupon would make decisions, in your favor, a lot easier. Just a thought. Regardless, keep it up. You guys make affordable, quality pieces. Thank you. Honestly. Thank you for what you guys do!

Good customer service.

Quick response on any question I had

I have arthritis in my hands and fingers which made it almost impossible to take down my 9MM. The extended slide lock lever works better than expected! I wish I would have changed it years ago.

Great products, great service, fast shipping. What's not to like?

Great company

Fits my G17, P80 build perfectly!

Every Echelon needs this upgrade.

Only had 1 baseplate in stock. It would have been nice to have options and purchase multiple.

100% satisfied with my purchase. The item were as described and arrived quickly.
