Factory accessories give the best results
I've had my older-model VHS shoulder holster for awhile, and I like it a lot. I thought it might work a little better with tiedowns, and I tried some random ones I had around. That didn't work that well, so I found out that Galco sells the complete tiedown set for that exact holster, and I ordered it right away. Everything fits as it should, and the tiedowns keep the holster and mag pouch from swinging forward when you bend over.
Very professional equipment that I'll be happily using for years. Highly recommended.
