S&W M&P 2.0 will not cycle with dead air suppressor. Does anyone have a similar problem or possible remedy? Several 9mm loads failed from 115 grains to 147 grains. Any and all help would be greatly appreciated.

Will it cycle / function normally with out the dead air suppressor ...
with factory ammo ... don't test with reloads .
Could be gun related problem , ammo related problem or suppressor related problem ... you have to isolate the problem before you can address it ... And details matter ...any modifications done to gun ?

Are you using a muzzle booster / Nielsen Device?

Gun is brand new. No modification. No problems cycling without the suppressor. Several types of ammunition used without incident.
