I had to order the NcStar Tac list, amazon had it for little under $30. Its a wicked tight fit on my 17 and was finally able to put some rounds on it. Approx 100 so far and it still lights up. Unfortunately, there's no strobe function but for the price...so far its a winner. Im still grouping shots with the added weight. I will make an update after more rounds are run through it. Oh yeah, it'll light up a room with no issues...
