5.7 Rock with RDS PA SLX RS-10 and 25 rounds of goodness

Needs a threaded barrel!
Why?
Some want it to suppress it. I got one because without it the Rock has the shortest barrel between the 57 and Five-seveN. With it it’s the longest. Presumably, given same conditions, would make it the fastest. Which seems to be whole point of the caliber.

fair enough, but its my carry pistol, so longer is a eh.

My carry pistol has a threaded barrel and it doesn’t take up any more space than the holster did without the threaded barrel so doesn’t seem like a penalty to me. Ymmv. Extra velocity on 5.7 is always a win.
