Hope they got the extractor fixed.

The 10mm runs up to 37.5k PSI and the .357 Sig up to 40K PSI. It's the same case except for length. I a .357Sig barrel and in my M&P40 it won't get through 5 mags before it's starts failing to extract. Cleaning the chamber fixes it everytime. It runs .40 for days on end so it's definitely the extractor. I'd bet a six pack this is why they dropped the M&P 357 so quickly.

Makes one go HMMMM.
The .40 was the only one to fully penetrate the block. The 10mm didn't.

Which video was that in? Were the rounds matched as far as bullet style? .40 Underwood Extreme Penetrators going against 10mm range ammo wouldn’t be a fair comparison. 357Sig is supposed to be good on engine blocks but won’t penetrate bulletproof glass. 10mm Underwood 140gr Extreme Penetrators will go through bulletproof glass as shown in the video below.

Nice review @RugersGR8 I wish he could have gotten target ammunition loaded to 10mm standards, the Armscor has a velocity claim of 1008 fps so it a download 10mm.

Wish he would have tested their practice ammo for the control group.

May not have made a difference as the defender and penetrator rounds scream in the lighter rounds.

I’ll take the G20SF all day long. The G29 is okay but really has no real advantage as you sure can’t pocket carry it like a G26 or G27.
Don’t know about the M&P , but the glocks are supper reliable.
