RA9T
Outstanding real world performance in lots of OIS (officer involved shootings) from several large departments for decades.  
Outstanding gel performance.  Not +p, not harsh on the gun.  Doesn't suffer much from short barrel.

Where are you finding it? I used to use it until Winchester cut us off.

I agree 100%. I put that in any 9mm I carry.

We did some redneck water-filled milk jug tests on that ammo and they are really nasty looking when they open up...

It may not be the length difference.

The longest length hollow point loads I've seen are the Remington 147 grain bullet loads.

The problem with those is fitting some nicro pistol magazines.

Most 147 grain bullet loads are shorter than those though.

Early 147 grain bullet ammo had a problem with so little powder, they wouldn't fully cycle all pistols.

With newer powders, a lot of the 147 grain bullet loads have a bit more velocity now, but powder capacity is still limited.

With a new Glock 43, maybe an issue with a borderline weak powder charge and stiff new springs.

Maybe the 147 grain HST load is just milder than some others.

That wouldn't be a good thing.

Federal did discontinue the +P 147 grain HST load.

There wasn't much difference in velocity, but some difference in recoil.

I like 147 grain bullet loads in short barrels, because they are mild and they lose very little velocity, compared to a standard 4 inch barrel.

124 grain bullet loads have just barely more recoil, but a lot more muzzle blast.

The additional powder with 124 grain bullets, along with the recoil is likely enough to move the slide a bit more strongly.

The 124 grain bullets do lose more velocity in short barrels, compared to 4 inch barrels.
