Extended Cylinder Release — S&W J-Frame
Extended Cylinder Release — S&W J-Frame
A drop-in extended cylinder release for the S&W J-frame, with a larger thumb pad for faster, surer cylinder operation. The factory release on a small J-frame gives your thumb very little to work with, especially in a hurry or with gloves on. The larger pad gives you more leverage and a positive surface, so the cylinder pops open cleanly every time. Best of all, it is a true drop-in upgrade with no fitting required.
Why it matters: opening the cylinder is something you do on every reload, and on a small revolver the stock release is easy to miss or fumble under pressure. A bigger, more positive pad makes that motion faster and more certain, which adds up whether you are running a timer or just loading at the range.
Who it is for: J-frame owners who want quicker, surer reloads, shooters who run gloves, and anyone who has fumbled the small factory release.

FREQUENTLY ASKED QUESTIONS
-
Federal or Remington & others makes works the best with the .025 thick Full Moonclips, which fit all the .38/357 standard moonclip. They allow the cartridges to have some movement or wiggle so that they will fall right into the chambers once properly aligned. Winchester brass does not work at all as the groove width is too tight/small.

-
There is no SAAMI specifications for the extractor groove and each manufacturer makes them as they want. The following list gives you a great example. This is why the diameter size of the brass is critical to proper loading, unloading and fitment. Cartridge diameter too big and moonclip too small causes the moonclip to bend. The cartridge should rotate within their respective place and wobble slightly when all cartridges are loaded.
