I have a gen5 19. Was looking for a threaded barrel and came across a shadow systems blem barrel at a great price. Will this fit my g19? Thanks

You can, but Shadow Systems like to make the barrel "block" (I'm having a brain fart about what it's called) a little oversized, so you may need to fire fit it to your slide before it's 100% reliable.

Barrel hood.

Ok, thank you

All gens of G19 share the same locking block fit and barrel compatibility. Some manufacturers make separate Gen5 barrels where the length of the threading is slightly different to accommodate things one attaches to the barrel (e.g., suppressors, comps, etc).

My purpose is for a suppressor. How much does the length of threading really matter, or should the shadow systems barrel work? For that matter, would an oem glock gen4 barrel work in the gen5 slide then?

It most likely will work; however, keep in mind that that slide, barrel, & suppressor are all made by different manufacturers, so occasionally problems creep up, such as more space between the suppressor and slide than you'd like.

If they're both G19s, then yes, they're interchangeable between all generations of G19.

FYI, Gen5 standardized the locking blocks for G17, 17L, 19, 26, & 34 to fit the G19, so you can do things like put a G17L.5 barrel in a G26.5 or put G34.5 barrel in a G19.3.

Thanks for the info. Decided to try one and I will just fit it if it is not drop in perfect.
