Well, I think I am preferring the 197 - while it doesn't have the penetration of the 195 - I have read some impressive tests members of various boards have done. I think the expansion is worthwhile compared to the yaw of the 195.
At first, I loaded up my PS90 with 195 - but after I shoot the current mag, I may keep 197 in it.
Also, while my PS90 shoot at about the same point of impact with 195 or 197 - I have read that it makes a bigger difference in the Five Seven. Supposedly, the 195 is spot on with the sights and 197 is low.
I will probably only use 197 in the Five Seven when I get it. Since it has adj sights, I may just set it for the 197 only.
I get the ammo I can. Since my ps90 not used as a nightstand gun I shoot everything up. Of the 2? were does ss196 fall? I picked some up from a small shop for 10.00. The owner said he had it for awhile and wanted to get rid of it. Red tip instead of the blue my store has?
