This being my first shoulder rig, it may seem that I don't know how to rate one properly. It fits well, is easy to adjust, and looks good. As for the unique way it holds the piece, it leaves something to be desired. The spring end does a great job, but the muzzle end isn't well suited for different pistols. Some of mine fit well, others seemed to hang on snugly, though precariously.
As for the drawing and re-holstering - it really is easy and natural. The guide says to practice and it's correct: after a minute of practicing, I became fairly proficient. I like the system, really.
I wouldn't necessarily recommend this when there are others out there that are designed for a specific model, but it wasn't a terrible choice either. Perhaps a bit pricey, but I don't regret it.
Pros: Interesting retention system, comfortable
Cons: Not model specific
