    Bob-- does a magnet stick to the frame?

    Yea, that's the quick test. Either way, my gut feeling is it isn't going to survive being fed a constant diet of +p. May be apples to oranges, but I know the HiPower's lifespan is severely reduced being fed +p, even with the heavier 18.5lb recoil spring. There are so many inexpensive modern 9's now (Ruger offerings come to mind) that can eat +p with aplomb, risking your safety and the longevity of the older pistol may not be worth it. It's not just whether the metallurgy is good enough, but can the recoil system handle it. I don't know if recoil springs for a P38/P1 are swappable, and where would one source heavier springs anyway.

    I haven't chronoed the lead version, but the 147gr JHP went 1,115 fps from a 3.8" CZ and 1,127 fps from a 4" FNX - both for 5 rnds at 5 long paces and 65 deg F.

    All the Buff Bore stuff I've chnoned was right on advertised vel and had very low ESs -- accy/velocity will be gun dependent.

    FWIW,

    Looking at the length of the Accurate 36-142H, .585", I put it into Quickload at a loaded length of 1.169", and using 8.5gns of Blue Dot gave 1167fps from a 4" barrel @ 37kpsi and 119% load density. Blue Dot being a flake powder is fairly easily compressed. Quickload shows 38,500psi for 9mm+p
    FWIW

    The .25" diameter meplat of 36-142H will probably drag against the front of the typical magazine box at max. 1.169" OAL.

    Could you run Quickload again reducing the charge to 8 grains of Blue Dot at OAL 1.14"?

    Also would be curious about 3.5 grains of Bullseye at same OAL if you have time.

    Now this would be a cool test. I may have to order some and give it a try. Thanks for sharing the info so far, it’s a great baseline just reading through the posts.

    I put it into Quickload at a loaded length of 1.14", from a 4" barrel
    8.0gns of Blue Dot gave 1135fps @ 36kpsi and 121% load density.
    3.5gns of Bulseye gave 884fps @ 20kpsi and 65% load density.
    4.8gns of Bulseye gave 1122fps @ 38kpsi and 89% load density.
    5.2gns of Unique gave 1101fps @ 35kpsi and 99% load density.
    8.0gns of AA#7 gave 1110fps @ 33kpsi and 92% load density.

    I did a little more testing with the Outdoorsman load. I moved the bullet to a COAL of 1.050" and got a 5 shot average of 1058 fps from a Glock 19 with a Lone Wolf barrel. Their was light leading and easily removed with a nylon brush wrapped with bronze wool.
    I did a second test by maintaining the COAL and increasing to 5.3 grains. (This was done for my curiosity and not recommended.) A four shot average was 1113 fps. Their was a notable change in the primer, leading in the barrel from in front of the chamber to the end of the barrel and a gain of 55 fps. The leading required a fair amount of time to remove.
    The ammo and gun were both at 60° F in the shop and went out in to 30° F air and shot within a few minutes.
    Accuracy testing with the 5.3 grain load was done. Here are the results of 5 shot groups at 15 yards off hand:
    Beretta 92F 5 3/4" with vertical stringing.
    S&W M&P 2.0 5 1/2" with vertical stringing. This was my competition gun and shoots very small groups at 50 yards with a coated 147grain boolit.
    Glock 19 with Lone Wolf barrel 4 1/4".
    Glock 19 with factory barrel 2.5".
    All barrels leaded their entire length.
    I'll get back with accuracy testing on the 4.9 grain load.

    I’ve seen two P-1 (aluminum alloy frame) pistols with cracked frames and would advise against using +P ammo in that type of pistol.
