Best treatment for walking pin: locktite or flaring?

[bczrx]

I have one significant gripe about my SP101 in .22lr [8shot] that I just got: the pin holding the front of the rear sight leaf in place walks to the right within 4 rounds.

Should I just 'locktite' it with blue?

Or should I use my pin punches and flare the ends of the pin so they don't walk?

I am fairly skilled at some of this gunsmithing stuff, but don't want to do what isn't necessary.

thanks

I generally put a slight bow in the rear sight pin to fix that. keeps it in place and doesn't make it hard to remove.

Does the pin stick out on both sides of the frame? If so, just flare the left ever so slightly and see if it stops it. Sounds like a 3 handed job

Most folks will add the slight bend to that pin. It's an easy way that doesn't require 3 hands & 2 monkeys!

+1 to contender. This is what I always do.

Pull the pin out. Whack the middle of it so ever lightly with a ball peen hammer on an anvil or back of a vice. Put it back in there. It should hold fast.

Another vote for a slight bend. I have never had much luck with loctite on smooth surfaces.

OK, slight bend is installed. I'll report back after the next range trip to say 'thanks', or 'what next?'.

Third option is you can slightly flatten the end of the pin with a hammer to make it tighter in the hohe. Doesn't take much.

You don't even have to pull the pin out. Just push it out half way, tap it with a light hammer and drive it back in.

Yeah, what Flash said!

I'll be the odd man out. I just dab a tiny bit of blue loktite on one end and problem solved (in all the revolvers I've had the pin walk). I might try the bend idea as it never even occurred to me!

Personally, I never bend a pin period. Why not? Because I have had to spend a lot of time and effort repairing various assemblies over the years that were secured by "bent" pins. Ever try to remove a bent wrist pin on a Stevens break open shotgun that "someone" thoughtfully bent and you would understand what I mean! I understand that sight blades are easily secured this way, however, I prefer to "stake" loose pins......................Dick :wink:
