Things I liked: The Airsoft version of the Sig Sauer STL-300J is loaded with cool features such as a 200 lumen strobe light and a red navigation light. It takes 4 AA batteries so powering this thing is inexpensive(they are included). It takes a bit of fines to toggle between strobe mode and permanent light mode as there are two buttons you have to press in order to change the mode.
Things I would have changed: I would have put in a laser instead of a navigation light
What others should know: This grip should be able to withstand .22LR recoil but I would not recommend it for anything larger than .22LR.
