"...please stand up."
I'm seeing two different 9mm bolts being advertised as the "Gen 2" Faxon bolt.
On one website, the bolt as the integral key, and the text says:
Improvements include cuts to ensure both Glock and Colt-style lower receiver compatibility. The key is machined directly into the bolt carrier - no fasteners to check or worry about.
On your website, the bolt does not have the integral key, and the text says:
The extractor has been upgraded from an internal "1911" style claw to an AR-15 pivoted and sprung option. For ease of disassembly, a standard firing pin cotter pin is used, and to ensure long-life, the carrier key is separate from the charging surface ensuring that the carrier stands up to any vigorous action - no sheared keys! A stronger firing pin rounds out the new changes.
Which bolt is the real Gen 2, or, to put it another way, which has the latest/greatest mods/improvements, i.e. which one should I jump on?
