I have found this load to be accurate and reliable in all of the pistols through which it has been chronographed as well as a Beretta PX4.
Here are some expanded Winchester 127-gr. JHP's. All were fired from a Browning Hi Power. The one on the left was fired into newsprint that had been soaked for 24 hours and then drained 30 minutes before shooting. The one in the middle was used to cleanly (and legally) kill a Texas whitetail deer when I was taking part in a state-sanctioned management program. It grazed the heart from approximately 10 to 12 yards (and I passed on a lot more shots than I took.) The deer dropped like a rock at the shot, kicked for a few seconds and died. The bullet on the right was fired into water. The 127-gr. RA9TA load is reported to be a very consistent performer and in my own informal, statistically-invalid, and "anecdotal" observations, it is.
I have noticed no really obvious extreme pressure signs using this ammunition; no more than say, Speer 124-gr. GDHP +P's or similar loads. Having said that, I would not use +P+ ammunition other than from the known reputable manufacturers, since there is no SAAMI pressure-rating for it.
Though not a round I fired each and every trip to the range, I've fired quite a bit of it over the past several years, usually in Hi Powers (using 18.5-lb recoil springs) or Glocks. I think it is probably one of the top performing 9mm loads, but there appear to be very good SAAMI-rated +P loads, one of which would be Speer 124-gr. GDHP +P. I believe NYPD issues this load and that the NY Transit Police use the standard pressure version.
In my opinion, there are loads that perform nicely in 9mm in standard pressure, +P and +P+ and any
of them will probably do the trick with decent placement. If a person has concerns over using +P or +P+ ammunition, I honestly do not think that much (if anything) is being given up with some standard pressure loads. I say "some" because I just don't have information or personal observations with all of them. In my opinion, placement is power and perhaps
IF a standard pressure JHP gives up some power, it allows for more rapid follow-up shots? Just a thought, and perhaps one that is true for some folks, but not others.
Speaking only for myself, in the 124-gr. area, I'd trust Speer Gold Dot Hollow Points or Remington's Golden Sabers. I believe that Winchester has come out with a LE 124-gr. +P load now, but I've not tried it.
I have used Winchester's 127-gr. +P+ and Federal's 115-gr. +P+ loads with no problems, but these are the only +P+ factory rounds I've tried.
Best and good shooting.
