JWoww — I Got My Glock Cocked … Let’s Go Shooting!

Just when you thought Jersey couldn’t get more dangerous … TMZ has learned JWoww is strapped and training to fire handguns.

The “Jersey Shore” starlet hit up the Brick Armory indoor shooting range in NJ Monday with her BF Roger – and squeezed off several rounds from a .40 caliber Glock.

We’re told Roger’s a bigtime fan of the 2nd Amendment – and owns a 45 Springfield Armory XD Tactical … which he also brought along to the range.

No word on how JWoww shot – but we’re told she LOVED the feeling of cold steel on her skin … and is now considering buying a handgun of her very own.

You’ve been warned.
