"I'm very happy with my experience with Glockparts. I ordered Marine Spring Cups, a OEM 3.5lb connector and an OEM extended mag catch. Everything arrived as listed. Shipped USPS, ordered late evening of 07SEP, arrived on 10SEP. Very impressive, extra points for the speedy shipping. Shipping cost was standard USPS fees. GP also sent good status emails and my USPS tracking number arrived in my inbox before USPS even registered it. Great job GP. As I write this, I've just placed an additional order with them."
"I've ordered multiple times from Glock Parts and had a wonderful experience every time. Even on one ordered I called on something that wasn't their fault but they picked up the phone quickly and helped me and got my order shipped right then (I order a part that was back ordered and didn't realize it)."
'I'll recommend in deed!'
"I am very satisfied that i purchased the products from here, i'll recommend in deed! Distance is huge (from Colorado to western Finland)but the shipment was nicely fast!"
"I've ordered several things from this place and my experience has always been great! Fast shipping is a plus! Every order I've placed, I received within 2- 3 days. Check them out the next time you need mags, springs, barrels, etc!"
