Which would you buy if you could only afford one, like me ... trying to decide which one to get?
10.5 usually needs some parts upgraded to work 100% out of the box if that makes a difference.
The only thing it may need is an extractor upgrade kit which is a very cheap fix. The 10.5" models being sold now may already have the extractor issue fixed.
Fingers crossed its fixed,
I was told the same thing, just got its tracking number today!
I bought my 10.5 in December, got it in late January. Mine must be the factory upgraded gun, I have shot around 1000 rounds and the only issue I had was on my last outting when I forgot my mags and had to borrow a LAR-15 mag with the grey follower, I had 2 rounds not feed right and the bullet actually pushed into the case. With the factory 5 rounder and the 2 LAR-15 mags I own (orange followers) I never had a single issue EVER.
