Not having a Glock, never thought about wanting one, but since they came out with a model for the SIG 320 and I just happen to own one and it was on sale, I bought it. Upon arrival , unboxing, it took less that 10 seconds to drop the SIG in and ready to go. with the weight spread out, it feels lighter complete than with just the weapon alone. well balanced, popped a red dot on and dialed it in, very little felt recoil, and hitting steel plates at 75-100m's with ease. It feels so light that when I let the wife hold it, she asked, is this real? LOL, Light weight, easy to put in and remove the weapon and an increase in range. Glad I bought it. Now I'll get more time in with my 320 on my range
