Jackhammer extended magazine or laser?

So I bought the jackhammer knowing it is 'UP' just because I wanted it.
Playing around with the laser sight and the extended mag is a bit hard to choose, laser sight lets me kill someone quicker (or so I believe) but extended mag can be a life saver if another guy turns up.

What do you use and which seems better?

Does laser even do anything on shotguns? I never noticed the spread getting tighter with one.

Can't go wrong with extended Mag on shotguns imo.

I'd recommend Extended mags

Extended mags no competition. The CoF of the Jackhammer is already small.

Use burst mode and always try stop with 1 shell left for quick reload.

IDK why people call this gun underpowered, I personally love the thing.

here's some random clips i tossed together, most of which is jackhammer gameplay.

I run semi and extendo because i dislike burst fire for when i know 2 shots will be enough

Extended mags all the way. 3shot burst, 3shot burst, 2sec reload rinse and repeat.
