why do Glock 34/35 have cutouts on top of slide?

[motorwerks]

I would rather the slide be solid with no cut out. Nice place for small rocks and dirt to get into.

two things come to mind....
Are you using your new 34/35 as a shovel?

and have you seen the Beretta 92 series?

[motorwerks]

Keep muzzle flip down by allowing gasses to escape in vertical direction. Maybe lol.

not on the 34/35 the barrel isn't ported.

Thanks!

- Heine Straight Eight rear
- Dawson Precision Fiber Optic front
- And don't forget the Tru-Grip... Love it!

One more for fun:

Nice choice in sights.

I called Glock after I got my G35 with the same question a couple of years ago. The reply was "weight reduction". I was also told that the G35 slide will do fine on my G22 if "need be", since the weight is similar, though not identical. (G22 and G35 can exchange parts if needed).

Yup, weight reduction is all.

Kyle, a top slide from 4" barrelled G-22 can be replaced with slide from 5.5" barrell

-ed G35?

I'll have to try that sometime.

[Kyle1886]

Squid,
I haven't tried swapping either---and I don't necessarily believe everything that Glock customer service says. However that is what the gent told me. I know the internals are the same.

Maybe one of these days when I get more adventurous, but I suspect it requires the "slide assembly" swap on the frame.

Stay safe

As has been said, it's for timing the action. With the same cartridge, a slide of given mass will recoil at X velocity. If you make it heavier, it's slide velocity will be reduced accordingly.

I'd imagine that the slide velocity is chosen carefully for optimum reliability and longevity, so lightening the slide of the G34/35 models brings it down to G17 like speeds and allows the use of standard recoil springs (another part of the tuning equation) AND allows it to fire lighter loads that wouldn't fully cycle a heavier slide - a boon to a competition/game gun.

Also, now I want one.
