What are "slide ports"

[NicVerAZ]

Straight out of the USPSA rules (for Limited):

17 Slide ports permitted Yes

Ok... What are slide ports? Cannot find anything on Google.

Thanks!

Holes in the slide, like on the Glock 34, 35, and 24. The barrell cannot have holes/ports for Limited, but the slide may be ported.

Next question: what are they supposed to bring?

Thanks

Weight reduction. More slide speed. Awesome looks!

I believe the concept is that much of the

muzzle lift (recoil) of a semi-auto is the

mass of the slide coming and going during

recoil.

So, the less mass (weight) of the slide, the

less perceived muzzle disruption (recoil).

Helps with muzzle dip when the slide goes forward into battery. With the weight reduction on the front of the gun it makes side to side movement quicker.

For gun with compensator, the mass of the slide may be critical as it reduce the slide is recoil operated. So a less mass slide (ported slide) will run easier. In non comp gun like G34/35, porting the slide allow to have a similar weight slide to G17/22, and then use the same springs ratio.

And another plus for ported slide, it allow a better barrel cooling.
