In my younger LE years (80's) I carried whatever I could find on the shelves, but preferred 158gr LSWCHP +P. I also carried the original Federal Nyclad 125gr standard pressure and 125gr +P loads, and their 158gr Nyclad SWCHP +P. I even tried the Winchester 147gr +P JHP. I still have a couple boxes (give or take) of the Fed Nyclad 158gr +P and W-W 147gr +P in amongst my old ammo. I eventually settled on the Rem version of their 158gr LHP +P, after being told that the CA state ammo contract testing of the time showed it might expand from a short barrel. I think I still have a couple boxes of that, too.
As the 2000's rolled along I was shifting from using the older 158gr lead HP's to some of the newer JHP's being refined to perform from short barrels. After seeing how the Rem 125gr BJHP/HPJ (GS) +P, the then-new Speer 135gr GDHP +P and the Win 130 RA38B +P (bonded PDX1) did in some gel testing, I settled on those for my +P capable Airweights and .357 M&P 340's.
I picked up a nifty 37DAO, built on the older Airweight 37-2 frame for a canceled overseas police contract run, and I limited the ammo used in it to only standard pressure. I used Fed 110gr Hydra-Shok and Win 110gr STHP, and hoped for the best. I eventually settled on the Hornady standard pressure 110gr FTX Critical Defense, as it was a surprising tack-driver in my snub, in my hands.
I'm still using all of those loads in my J's.
FWIW, this is a small screen shot of some of the original Speer Tech Data Package in 2003 that was available online many years ago, when they were first developing the 135gr GDHP for their new +P load made for use by NYPD for their approved J-frames. They designed the then-new 135gr GDHP because they decided the existing 125gr GDHP bullet couldn't be made to meet the performance objectives of their LE customer.
This screenshot was comparing how the new .38SPL GDHP load compared to the existing 124gr +P GDHP 9mm load used by NYPD.
Also FWIW, when the 135gr +P load was still new (before it was called Short Barrel), I saw some tested at a hosted gel shoot, fired from a borrowed M&P 360 snub. The organic gel block had been sitting in the sun for the afternoon, and had been used for other 'test shots', so it wasn't like it had been earlier when taken from the mobile gel lab refrigerated trailer and checked with a BB shot for 'calibration'. It was a 4LD test shot, though, and the fired rounds all reached just short of 11" in those conditions. The owner of the M&P 360 had been carrying Rem 125gr GS +P, and he wanted to test those, which was done after the new Speer loads had been fired. The grungy and tarnished 125gr +P GS hollowpoints performed virtually identical to the Speer GDHP in that 4LD gel block.
Once my agency started stocking our range ammo shelves with both the new Speer 135gr +P and the Rem 125gr +P, I started carrying whichever was available at the time. I added the Win RA38B later on, after seeing how it performed similarly in another hosted gel test, fired from a borrowed 642. When my agency started receiving it for range/off-duty use, I started using it for my range work. I also went to the local Win LE Distributor and bought a couple cases of it at individual officer pricing, which I think was $249.99 for a 500rd case. I still have a little less than a case of it left. The Win LE rep said that it was the same thing as the commercially packaged PDX1 130gr +P bonded .38SPL load, but packaged in 50rd boxes for LE sale/pricing.
