First time posting, long time 'guest' reader. I have an H&R 929 .22 cal revolver I inherited from my father-in-law. When I took it to the range to test fire it, it failed to fire roughly 30% of the time due to light hits on the rounds. I've been reading through the older posts and found the solution for the constant misfires--broken plastic on the hammer end of the mainspring guide assembly. Just received the replacement from Numrich today (ordered the all metal one). It fits normally and allows the weapon to cycle normally, but I'm concerned about the mainspring seat that came with it.
The original seat is rounded to apparently allow it to rotate as the spring guide angle changes during cocking and firing, but the one that came on the replacement is flat and rectangular, and fits loosely in the channel machined near the butt. Also, and my main concern, is the new one is narrow and only about half the width of the frame, which can allow it to move from side to side. For those who have replaced theirs before, is this a problem, or should I try to install the old curved seat in its place? Not sure how to safely compress the spring outside the frame and get the guide through the hole in the seat so I can pin it and re-install in the weapon. Recommendations please!
