S&W M&P 2.0 10mm

[DonD]

I have a nearly new 10mm. It's totally reliable with my reloads (155gr SWC polymer coated slugs), Underwood 155gr and Fiocchi 180gr JHPs @ 1250fps.

It has not had issues with undesired mag drops. It has the heaviest weight recoil spring assembly.

So far, it doesn't like the 200 and 220gr Underwood hard cast slugs.

It's not limp wristing, I shoot well with my S&W 500 Mags.

I wonder if a noticeably tighter grip would improve reliability with those Underwood loads?

I have 3 mostly full boxes of that ammo, close to $150 in ammo and I want to be able to use them. Thoughts? Don

I blasted through a bunch of $$ worth of Underwood 200 and 220 grain a couple weeks ago in mine without issue. Not a single FTF, or any sort of problems. I was actually considering picking up their 200 JHP as a carry round.

Interesting, have you made any modifications to your 10mm? Thanks, Don

My M&P 10mm has been 100% reliable but I haven't tried any hard cast ammo. I prefer the jacketed 180-200 grain ammo.
