    I sent them an email inquiry about a slide they responded quickly. I then placed my order for the slide, blank moa plate , glock case, and barrel nut. All came in, no backorder and it was at my home in about 3 days. The slide is precision right on , looks great on my glock 31 and is smooth as silk when racking one in. I would reccomend this place to everyone. Top notch service and on the spot products. This company is a 5 star company!

    Excellent product, excellent price, excellent service. I am happier than a fat man at an all you can eat restaurant and thats my take on you guys. The Glock Store should take lessons from you folks. You did me right and I am gonna tell all my gun buddies about you. I thank you very much, John D. Lowery Manteca Ca.
