Since I started making the MGSL back in 2001, a whole number of people have used them to improve the accuracy of their Glock pistols. And some people were quite skeptical at first.
However, many of those folks have been repeat orders.
I have a 100% satisfaction guarantee on my MGSL, and a no BS policy. If anyone has any problem, they get a full refund - including the shipping costs.
