Hey guys,
I'm new to the forum, but have been shooting Ruger SA revolvers since I was a kid. I have a couple questions regarding my 1978 .357 NM Blackhawk, which I believe has been in the family since new (Dad bought it from my Uncle, then years later, he gave it to me). I carry this gun everywhere, but don't shoot it as often as I would like to.
The other day the wife and I were doing some target practice and I noticed the rear sight blade was popping up on one side. I took it apart to find a couple crushed springs. As things go, I couldn't stop there. I began checking everything out. When I checked the cylinder alignment on lockup, there was a fair bit of slop, and the cylinder always stopped slightly too far clockwise (looking down the barrel). If I rotate it counter-clockwise, it is perfectly aligned, but it always rotates back out of alignment.
Upon tearing it down, I found that the cylinder latch has play, both on the trigger pin, and in the frame slot.
What is the best course of action here? Should I fit an oversized cylinder latch? Shim my existing cylinder latch? BTW, I haven't noticed any shaving.
I can feel a fair bit of play between the cylinder and the base pin. Should this play be there? What are your thoughts on oversized base pins vs new Ruger base pins?
Also, regarding cylinder endplay, If I hold the cylinder back, I am getting about .005"-.006" clearance (hard to tell exactly because of the play between cylinder and base pin. If I hold the cyl forward, a .002" feeler gauge won't come anywhere close to fitting between cylinder and barrel. From what I understand, the .005"-.006" clearance is within spec, but should the forward clearance be as low as it is? Is this too much endplay...and if so, what is the best way to tackle the problem?
Any other recommendations regarding things to work on while it's apart would be appreciated.
Thanks!
