I use the Tru Oil, and usually 4-5 coats. When last coat is fully dry (I let dry 7 days), I rub down with Mothers Mag Wheel polish. I used to use Rotten stone slurry, the Mothers is much easier and less messy and gives me a nice satin sheen, not glossy.
I know what you mean about a rear sight. I needed one for a Mod 14 about 10 years ago, and finally found one for $125. I had to get it to get the gun back to original.
The bottom pin always stays in the grip. The top hole is where the "lock down" pin is installed. This just holds the safety lever down, so it doesn't interfere. Some people had difficulty gripping the gun properly to hold the safety down.
Hoping you are familiar with "correct" side plate removal. If not, please look up a few you tube video's on the correct way to disassemble a S&W revolver. The first thing is the "correct" screwdrivers to fit the screws. If you don't have one, don't start until you do, to prevent any damage to...
I have removed thousands of sheet metal screws, (and replaced them) in the aircraft I worked on in the USAF in England and France. You didn't have power on the flight line back in 1960 for drills, and battery drills weren't available then.

The #1's
The .32's
I personally think the price is some too high, but the limited production of Mod 35's push's the price up. Lately I have been seeing Mod 17's priced that high and they made a whole lot more of them . When was the last time you saw a Mod 35 for sale? At any price?
How the gun fits your hand can make that much difference at 25 yards. The part of the finger that presses the trigger can be too little or too much causing you to pull or push your shots. Shot from a solid bench rest with trigger slowly pressed straight back can tell you a story. Here is a...
Some 22RF cartridges are "dirtier" than others. If you find a brand that works good with your revolver stick with it. I have a 617-6, and it had "sticky extraction", I did the reaming of the chambers with a Manson Finishing Reamers, and have no problems with any brand now.
