was thinking of getting a GLOCK 17 and can't decide on a gen3 or 4.
Go over to the Glock Talk forum and do a search.
We've had several threads over there and the
double-spring guide rod "issue" has been praised
as well as reviled over there ad nauseum
The only conclusion I was able to draw from the many
threads is that the satisfied users of Gen 4 glocks
outnumber the dissatisfied ones like 10 to 1 or something.
But I speak from personal experience when I say that my Gen 4
Glock 17 never failed to fire nor failed to eject (FTF/FTE)
after 1,800+ rounds of various loads. I also have both the
original double spring recoil guide and the "O2" or second
version that Glock issued to owners who were "concerned"
with the "01" guide rods. Hey, it's free! And I will have to
replace the guide rod someday so why not ask for one,
The other evident thing I discovered in the discussions is
that most of the "naysayers" who speak ill of the Gen 4,
by their own admission, do not own or have fired Gen 4 guns!
Their justification is that they won't buy a "faulty" gun but
instead accept hearsay testimonials about the "Gen 4
problems" as gospel truth. If most buyers of Gen 1 guns
were as finicky as some about the Gen 4's, there wouldn't
have been Gen 2's and Gen 3's, because rumors and allegations
would have stopped Gaston's progress dead in its track!
Go buy the Gen 4! It's got a fantastic grip (or set of grips)
that feels better in the hand than any "grip reduction" job!
And the double-spring guide rod reduces felt recoil significantly!
Here's my Gen 4 G17, now sporting a G17L barrel for target shooting
and a Streamight TLR-1 Strobe for home defense:
