Well, I've been bored lately and I'm one of those guys who prefers barstock and forged stuff over MIM and castings so I ordered a stainless barstock extractor from Cylinder and Slide and a stainless, barstock, lightly extended mag release kit from Ed Brown to outfit my new, NRM, Gvt. model, Stainless Pony. Both parts were just a bit excessive in tolerences ( the way I like it ) and I spent a few relaxing hours honing and polishing and tuning everything up....ahhhhh so sweet.
The C and S extractor had just the right overall length and was just a couple thousandths tight in the firing pin stop channel, I evenly took just a bit from the front and the back of the channel and polished it up for a nice, tight interference fit with the firing pin stop. There were also some tool marks on the top and the bottom of the whole length of the hook so I judiciously polished those off and finished it with a light wire wheel and fine valve grinding compound to give it a dull sheen on those two surfaces. I then gave it just a bit of a bend toward the hook and assembled everything. It passed the bench test for extractor tension so hopefully all will work out fine.
The mag release to a bit of trickery to get going right. The overall lenght of the catch screw/lock and the overall tight tolences of the release caused a bit of mag binding upon release so I trimmed the catch screw just a bit and also heavily polished the surface opposing the release stud. The new catch and the screw/lock was a bit rough externally and tended to actually unlock itself from the gun so I very carefully gave it a light polish to remove the tool marks and also dehorned some of the edges of the mag catch while I was at it. After a bit of cleaning in the sink and then a oil wash and dry with some WD40 I lubed everything up a bit with some Tetra Lube and whhhaalah!! The catch still feels a bit rough against the inside of the frame but I will let that smooth out naturally.
Next week: a tool steel sear and disconnector!!!
Mmmmmm, I love my Pony!!!
