Gun Pro announced the introduction of handgun sights called the Delta 1. The Delta 1 sights claim to overcome some of the perceived problems with traditional post and notch sights. Here is a video from the company that explains the sights:

These are not night sights that are self-illuminated in low light. The sights are machined steel and made in the United States.

Delta 1 sights are being made for the 1911 and the Glock platforms. The company also has plans to introduce them for the M&P series of pistols from Smith & Wesson. The Glock version of the sights are fixed and carry a suggested retail price of $89. The 1911 sights are adjustable and have a MSRP of $119.
