"I think the majority of us that have been around guns and ammo for decades, and have shot upwards of 500k rounds in our lifetime, stick with common manufacturers and well tested ammo; especially in defense ammo".

Yup. Though since I've only been shooting handguns for seventy years, I can't claim to be experienced.

BTW, that 4th link gives 343 ft-lbs out of a 1-7/8 barrel vs 295 for a standard pressure 9mm. Again at only five times the cost. I think I will stay with the anemic 147gr 9mm.

I didn't start reloading .38Sp until 1965. I like them OK, and have only blown up one gun.

For me, a heavy standard pressure 9mm in an Airweight J-frame lightened to 12 oz with titanium cylinder is just about the perfect blend of power, weight, recoil, accuracy, eject/reload speed, and bullet expense.
