9mm Buffalo Bore 147gr +p vs G9 124gr +p woodsmen for Predator defense?

[260284]

FYI...P365 does not like hot/heavy hardcast loads in my experience. I have 3 p365 pistols and none are fans of +p heavy/hardcast loads from both buffalo bore and Underwood. I got a response from Underwood that SIG specifically does not recommend heavy +p rounds in the p365 chassis despite the only info I can find from them stating the p365 will handle factory +p loads. Underwood was the worst of the two but I had cycling issues from both.
Mine will all shoot any other +p jacketed or hollow point rd I've tried just fine, but the heavy (over 127gr) lead stuff has had feeding issues in all 3 of mine so I avoid it...practice extensively with what you plan to carry, POI shift was notable for me on the hot/heavy loads that did cycle.
They all cycle +p 124gr copper jacket flat nose rds perfectly fine. Not sure what it is about hot heavy rds in the p365, but im not the only one to have issues there.

I have shot the Underwood 147 cast in my 365 and it fed and shot them the best of any ammo I have tried in it. I am using their coated version though.

You would think those heavy loads would be slamming that little pistol around pretty good, to say nothing about that stock spring.

I have shot the Underwood 147 cast in my 365 and it fed and shot them the best of any ammo I have tried in it. I am using their coated version though.

Was using the same. Two different batches, did the same thing.
Was leaving tiny rings of the case in the chamber, next round wouldn't feed. I figured it was the gun. Tried in my two others, an xl and another standard 365, same results.
I was told directly by Underwood they do not recommend that ammo in the P365, nor does sig recommend the use of heavy hardcast +p loads in the 365platform...I got no such verification from Sig.
The copper jacket flat nose 124gr +p from Underwood works flawlessly, so Ive just stuck with those.
I had similar failure to feed issues with the Buffalo bore but without the tiny ring of case material left in the bore. Maybe im just lucky and got 4 bad boxes/batches of ammo...and yes, I clean my guns properly and regularly.
