Third purchase from this store. Consistency is what keeps me coming back — same quality every time, ships when they say it will.

Did a lot of research before pulling the trigger on this purchase (pun intended). Read reviews on 3 different sites, watched YouTube videos, and ultimately went with Americans Gun because of the price and shipping speed. Not disappointed. Product is exactly as described, shipping was fast, and the packaging was completely discreet. Already eyeing a few more items in their New Arrivals section.
