Caveat: I'm pretty new to AR pistols so I'm still learning.

So I was at my local range the other day that had a Saint Victor pistol, 5.56, with a 7.5 barrel for $869. That seems like a pretty good deal and I've been thinking about getting it to keep as a truck gun.

After doing a little research I've read that the 7.5 barrel will reduce the velocity of the 5.56 to nothing more potent than a handgun round.

I know it's not recommended to drop shorter than a 10.3 for 5.56 but could a 7.5 be that bad? Anyone have any experience with the Saint?

Thanks for the input.
