I bought a Glock 43 as a pocket gun/grab-and-go gun and it now has 500 rounds in it. Here are my impressions at that 500 round mark.

Upgrades in the gun:
1. Trijicon HD sights: http://amzn.to/1Y0fpiu
2. Ghost Edge trigger connector: http://amzn.to/1THEcT8
3. Tango Down Vickers +2 mag extensions: https://tangodown.com/shop/vickers-tactical-2-magazine-extension-for-the-glock-43-vtmfp-006-43/

I am not paid for this review in any way, and was not given any of the items in this review. I bought them all at full retail.
