I see no issue with it. I too asked this question awhile back but didn't receive much response. A phone call to dw and my Vbob now has a 20lb recoil spring. I received as a pay back 1000 rounds of win ranger t +p
. I plan on using that as my carry ammo and have run about 250 rounds through my Vbob with no issues.
Like I said if you plan on shooting alot of it I would suggest upgrading to a 20lb recoil spring, Saves the slide and frame abuse caused by +p ammo.
