no.... it isn't.
Regardless of how long your sight radius is, the sight alignment will remain the same. Aligned sights are aligned sights. Traditionally an increase in sight radius was indicative of a longer barrel which many still believe increases accuracy which is also false. An increase in barrel length increases velocity which translates into better long range accuracy not necessarily an improvement in the barrels inherent accuracy.
If sight radius were important, why is it that my performance with my G17 and G26 are near identical? In fact I've shot the dot drill with my G26 without sights and still managed a 2 inch group. Odd??
On a side note, sight radius has no effect on shotguns with bead sights. Again, if sight radius is so important why do shotguns only have a front sight?

Try different ammo. Ranger LE HP 124 gr was the most accurate.
With WinClean 124gr I could get consistent 3"-4" groups, off hand on 25 yards but with Ranger ammo the groups shrinked to consistent 1"-1.5". It
was unreal.
If you handload, Hornady bullets are your best bet.
How accurate do you want it to be?
sounds like TDC is trying to suggest a software problem to a hardware soloution... sight radius does effect percieved accuracy because NOBODY holds a hamdgun pefectly steady while pulling the trigger...... here is the math done for you that shows the degree of error if the rear sight moves just 1mm.
My calculations are based on 1mm offset on the rear to front alignment, and it's effects on a target 7 yards away.
First, the data:
Sight Radius (in order of length):
Glock 19 ~ 5.98" (151.9mm)
Glock 17 ~ 6.50" (165.1mm)
Glock 34 ~ 7.32" (185.9mm)
1 mm movement on the rear of each of these sights (in degrees) and their equated drift on a target 7 yards away:
Glock 19 (0.37719 degrees) = +/- 42.138mm drift
Glock 17 (0.34704 degrees) = +/- 38.77mm drift
Glock 34 (0.30821 degrees) = +/- 34.432mm drift
The Glock 19 offers roughly 22% more error amplification due to sight radius @ 7 yards.
In case anybody was debating the Glock 19 vs 17 vs 34 based purely on sight radius.

Wes your calculations certainly should help those who fail to understand the concept. I would have thought this information was rather common knowledge, perhaps not the calculations, but rather the concept.

I get consistently better groups with the 26 than the 17 at any distance, unless using the Lasermax on the 17, strange but true. Many owners on GlockTalk attest subcompacts more accurate than the fullsize models.
ok, so it does sound like the longer the barrel and distance between the front and rear sights, the easier it is to shoot "accurately"? i do understand that all glocks will shoot just as accurately if mounted onto a stand (as the barrels are all straight). my question was to find out which Glock to get that would be more consistently accurate in the hands of a regular shooter (ie. hands move while aiming etc)...
An increased sight radius does not make you more accurate, it increases the gun's mechanical accuracy potential. Glocks are consistant until the barrel wears out (100,000s of rounds), shooter's and ammunition are not.

Thanks for doing the leg work Wes. Here's the good part for those that missed it. Assuming Wes' numbers above, the difference in impact is a whopping 8mm between the full size and the sub-compact, that is just under one bullet diamter(assuming a 9mm pistol). I can see that's going to mean the difference between a hit and a miss. This also assumes a 1mm misalignment. The shooter will induce more error than any sight radius or trigger ever will. Check Kaolorka and NAA's posts above, they unlike many understand what's important regarding "accuracy".

hey, what's up with the name calling? that is not necessary.
it is precisely the fact that shooters and ammo are not as consistent, that makes me want to get a gun that has an increased sight radius- to compensate for other variables such as (in this case) the new shooter.
