How funny. I was just coming in here to introduce myself and talk about Ben’s work, and the first thread I see is about his work. 
I’ve known Ben since he was just a wet-behind the ears wannabe gun guy. 
Just kidding. Ben is actually the guy who got me thinking about and learning about personal defense. I got him thinking about Glocks, then defaulted and went the way of an XD9sc for my first pistol. It wasn’t long after I realized my small hands had me pushing all my shots left that I decided to try something else, and went to the 1911 platform. Shortly after that, Ben, who had begun experimenting with his own Glock, came up with the earliest version of his reduction.
At his advice, I took a class with my SA EMP, and my Kimber Pro TLE/RL II. I had multiple failures during the class with both of my guns and became extremely frustrated. When I asked the instructor what I could do, his response was to “Get a Glock.” Of course, Ben laughed at me.
I went ahead and gave the EMP to my pops, sold the Kimber, and picked up a 19 and 21sf. Of course, Glocks don’t fit small hands well, so after having those cherries popped both of my Glocks went directly across town to Ben’s polymer spa.
Let me just say this: I won’t own another Glock without having Ben operate on it. Matter of fact, he’s got a brand-spanking new 19 on his bench right now getting it’s percfection improved. I actually initially got basic reductions on my 19 and 21sf, but after Ben perfected his extreme reductions, they both went back to him for workovers.
On top of that, let me just add that while Ben’s meticulous attention to detail is second-to-none in the industry, he’s also a stand-up guy who doesn’t hesitate to share either his stuff, or his knowledge. He’s one of the best friends I’ve got. Case in point: when I told him I had decided to get an AR finally, he helped me find a decent deal on a full LMT with a reliability workover by a reputable gunsmith. What a pal, right? 
Ben’ll probably be embarassed by this, but I wrote it all to let you know that I know firsthand what kind of time and energy Ben puts into his work. I also know how he respects and values his customers, as well as their time.
If you’re at all on the fence about having some work done, or you have a defensive tool that just doesn’t fit you like you want it to, Call BSS. You won’t regret it.
Btw…that 19 looks amazing ADH, and I’m sure you’re going to love it. Might as well call SAI, have them sell you another one, and let it go straight to Ben before it’s sent to you.
