Glock 34 frame compatibility

[VancouverS4]

I like my G34 but want to play around with a different set up.

I know a same-gen G17 slide will fit, but will a same gen G19 slide fit?

It's a gen 4.

No 19 slides are too short.

The locking block and barrel lug are different between the 17 and 19, you will have a bad day if you try it. Gen 5’s have the same dimensions now.
