Long slide glocks yea or nae? G21 vs G41

[Yycbulletsandbrass]

small correction for at least the 21/41 the long slide 41 is lighter. The slide and barrel walls are considerably thinner.

Still longer and bulkier.

Trendy ....lol. Just because you haven’t experienced a gain in performance doesn’t mean there isn’t one to be had.

From a recent article by Col. Kenneth Haynes (Ret.) - Tuesday, February 26, 2019

So you're worried about a 1.46" possible(mechanical only) difference between a standard size pistol and a long slide at 30 yards?! Are you saying you shoot well enough to notice such a performance change? I highly highly doubt anyone on this board shoots well enough to notice the potential difference the increased sight radius could have on down range performance. Curseyou quoted below is what people need to understand when it comes to sight radius. In a nutshell it's a gimmick that no one will ever reap the benefit of. If your skill level is high enough to reap the benefit, you don't need the minute gains it offers.

Does this answer the right question? Does a longer sight radius reduce sight misalignment? The important part of your post is not the arc at a certain distance. That is obvious physics and the appealing theory.

The question is "Does a longer sight radius reduce the occurance or degree of sight misalignment?" You post speak of a 1/16th error. Does a longer slide cause people to reduce their average misalignment?

For example if my sight misalignment is caused by poor trigger control when squeezing, my sight radius will have no impact. The gun to target misalignment is the same. If however the longer sight radius helps me turn a 1/8 mis alignment into a 1/16 then gigitygigitygoo.

I’ll just leave this with you. It’s a short version informative read. After reading it get back to us and let us know if it answers the right question OK?

Cheers,

Yes, the basics of sight radius and simply geometry/physics. Which does not take into account the ammo used, the sights themselves or the ability of the shooter. Are you also saying you can observe a 1mm/0.04" misalignment, at speed when competing? Sure.. The A zone on an IPSC target is 5x9" if I recall. Plenty of margin for error with the 1.46" of possible gain with the longer sight radius, and loss with the shorter. With an average of 24" from eye to front sight on a set of Trijicon HD sights(which are the same width as stock sights at 0.144") that equates to a 5.4 MOA front sight at 25 yards, or 6.48 MOA at 30 yards. Even the skinny XR sights would equal 4.6 MOA at 25 yards and 5.5 MOA at 30 yards. So your best groups possible are over 5 inches at 30 yards, if your ammo is consistent, if you are consistent(trigger) and your sight alignment and sight picture are perfect. I don't think you will ever notice nor be able to distinguish any gains from an increased sight radius. If you shoot 5 inch groups at 30 yards you don't need to worry. I bet the sight wobble from pulling the trigger is more than 1mm.

I will leave this here as well... Do you think he needs more sight radius??

Like curseyou pointed out, the key is proper sight alignment, sight radius is irrelevant if you can't align the sights and maintain that throughout the shot. Here's a secret, the iron sights are fixed to the gun and always aligned with one another. It is how you see that relationship between front and rear sight, and how you transpose that relationship onto the target that changes.

Here's some more speed oriented/action shooting.
