Mdx combat slide
Great texture parts are precise and can’t wait to shoot it as it’s my first build. My don and I are both using mdx so I’ve heard through mgb that these parts are flawless so we didn’t want to take a risk trying to be cheap

TOP QUALITY
Beautiful slide, perfect fit, excellent craftsmanship.

Awesome Product
I bought an entire slide kit and I am super happy with my purchase. The threaded barrel is awesome and the machining is spot-on. The internal components seem to be of good quality and function like they should. The sights suck and the rear site is able to be slid side-to-side with my thumb.

Great choice for your first build
100% reliability with Blazer 124 grain after minimal break-in with dummy rounds. When I first put it together I cycled several mags of dummy rounds through and did have some failures to go fully into battery. Kept adding oil to the barrel and connector and kept cycling dummy rounds and this malfunction didn't happen while shooting. It does not seem to like the Federal 115 grain however.

Good except for slide release spring
Everything seems good, works well, etc, except for the slide release spring. It sticks up too high and hinders the slide from moving freely. Tried to bend it and screwed it up totally. Remove the spring and it works flawlessly. Made sure I had it installed correctly, but 0 for 2 builds. Ordered some other ones. Hopefully that fixes it.
