I recently purchased a Smith model 43C in .22LR and .351C in .22 magnum. I was pleased to see that neither revolver had a lock.
The 43C's trigger is decent, where the 351C's is HEAVY! Apex says their J frame kit is not designed for the .22LR/.22 magnum J frames, and trigger jobs on .22 J frames can be hit and miss in terms of reliability. Any idea why the .22 magnum trigger is so heavy -- does the .22 magnum cartridge require more to reliably ignite it?
I read where #4 ribbed plastic anchors are the hot ticket for dry firing the .22's, got some for a couple of bucks, and am happily dry firing. The anchors are even a nice yellow color that makes them stand out.
These .22 J frames look like an ideal pocket kit pistol for an outdoorsy person.
