bolt cracking hyper frame??

[SIGSays]

if i get a hyper frame would i have to worry about bolt cracking or bolt wear??? for my mag?? my mags is one of the newer ones...... and a friend is selling his for dirt cheap so i thought i would take advantage of it after i get my valve replaced.........

Probally not. The bolt/sear chipping happens mostly in older Mags. Install it, fire 50 shots and check out the bolt and sear. Chipping? A longer on/off pin should fix it.
