cbrgator,
I used to work part time at a range where we sold thousands of rounds of the S&B Range Safe 9mm. We also sold the regular 9mm 115gr FMJ offiering. I've shot several boxes of the Range Safe and will offer the following, all pricing and availability issues aside:
The powder is apparently different than the regular S&B 9mm 115gr FMJ. (I've fired thousands of these.) The Range Safe powder is dirtier and creates more muzzle flash. The ammo makes for dirtier guns, but not as bad as the WWB.
The rounds do not seem to be loaded as consistently as the standard fare. I have no evidence of this, just my gut feeling.
We experienced several situations where the Range Safe had malfunctioning problems in particular guns. Our Glocks ran fine on it, but a couple of our Sigs had problems as well as an older S&W Model 39 and IIRC a 1911 platform 9mm or two. All of the above guns ran fine on the regular S&B loads. A customer or two mentioned they had problems with specific guns also, but I don't recall what guns those were.
Bottom line:
Try a couple of boxes in your guns. If there are no malfunctioning problems and you don't mind the dirtier powder, go for it. I would not hesitate to shoot it in my Glocks, BHPs, or S&W's. It's good practice ammo.
Cheers,
