I had the exact same thing happen with mine. The barrel gap was huge, like .009. I sent it back, and they narrowed the gap to .004. But they bubba'd the barrel, so I had to send it back again, and they replaced the barrel. All is well now!
U.S.A. –(Ammoland.com)- Once upon a time there were two J-Frames. Despite being brothers, they weren’t exactly alike. One of them was a big little gun, always powerful and loaded up with the latest features. The other was trim and feathery but secretly held three more shots with hardly a bit of recoil.
In the world of defensive revolvers, Smith & Wesson makes what can be considered the very best. For over 60 years now their small “J frame” short-barreled revolvers have been a gold standard for police and civilians alike. Though compact automatics have come a long way, boasting more capacity and reliability that is arguably just as good as any revolver, the J frame is still as solid as ever with advantages unto itself.
