Most of the super small, .380 ACP chambered pocket pistols on the market share the same problem: Their sights are barely useable. Innovative Arms can solve that problem with their Sight Upgrade.
The upgrade includes machining dovetails in the slide, the sights themselves, installation, and parkerization for $150. That seems like a deal to me considering that I have spent that much for a set of sights I had to install myself. The sights that Innovative Arms uses include a tritium front sight and a plain black rear sights that has serrations on its leading edge to aid in one hand manipulations.
They can also refinish with various colors of moly resin for and additional fee. Check out the Innovative Arms Sight Upgrade.
