I emailed a question on a Sunday expecting an answer on Monday. Eli replied with my answer on the same Sunday afternoon!

Installed this on a Smith 351 PD (22 Magnum J frame). Reduced the double action trigger pull from approximately 17 lbs to 10.5 using the heavier of two supplied hammer springs. Single action went from 2.5 to 2. So far, reliability has not been compromised in 50 rounds. As rimfire needs a heavier hammer strike for reliability, I’m very happy with this. Kit worked great!

Eli installed the spring kit as part of the Basic Action Job and it dramatically improved the trigger pull on my 640 pro. It's smoother and lighter while retaining the original strong trigger reset. Now the little J frame shoots like a laser as long as I'm not slacking off. Thanks!
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.
