Was worried about fit but it dropped right in on my Glock 43X. Works perfectly after a few hundred rounds. Very pleased.

Fast shipping, great packaging, product exactly as described. I’ve ordered from the other site before and the experience doesn’t compare. This store delivers.

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.
