Awesome
Slide is great. Looks great, feels great, paired wonderfully with my Strike80 frame. Mounted an RMR and had no problems at all.

Awesome
High quality product really awesome upgrade to my stock glock. It comes with standard glock sights already installed which was a nice bonus. The lighter weight was a bonus and found it to make follow up shots more accurate. This is already with an RMR cut so it is top of the line.

Highly recommend MDX Arms
Based on their shipping times and quality of the actual products I highly recommend MDX Arms to anyone considering getting into building. I can’t believe I didn’t know about them earlier on! As far as the LF19 slides, I’m in love and plan on purchasing another ASAP. You won’t be dissatisfied I’ve shot over 200 rounds no malfunctions.
