	I was looking at the trigger on my High-Wall, noting the hole behind the trigger blade. Down below it is the trigger weight adjusting screw. Seems to me that if I tapped that hole and put a headless set-screw in there, I'd have an overtravel adjustment. Has anybody tried that? - There's not a lot of overtravel in that trigger, but a bit less of it still might be nice. One thing that I've noticed is that a replacement trigger is quite pricey for that model. Just wondering if anybody here has done that modification and might have a word of wisdom for me.

	Lee Shaver is well known for working on the Win-Miroku trigger. Does a good job of getting it under 2# and very crisp. Simply remove the one (1) small screw that holds it in place and send him the trigger with sear attached. He was charging $35 for the work, but do not know his current price for same. The only drawback I know of is that the sear eventually wore out on mine (would either not cock or fired when the lever was closed) and had to be redone. I purchased a second trigger/sear as a spare so had one to shoot with while the other one was being reworked. Believe the second sear was $90 at the time.

	I own a recent Winchester Highwall in 32-40 that Steve Durren did a trigger job on - it's excellent and night and day compared to the other unaltered Miroku Higwalls I have. I also have one of the discontinued JP trigger replacement screws for a Miroku 22 Lowwall, and it too results in an excellent let-off.

	I have already replaced the trigger return spring and stoned the engagement surfaces, resulting in a nice two pound trigger pull. I'm just wondering if anyone else has tried the idea that I outlined for adding a trigger overtravel adjustment. Looking at the mechanism, this seemed like the easiest way to adjust overtravel.

	Never heard of it being done, but we'll be happy to hear how it works for you

	I'll look into it. Today I took the rifle out and shot ten rounds, getting the scope zeroed again and trying out the lighter trigger. It's a 270 WSM, I shoot reduced loads that push a 130 grn spitzer at 2,000 fps. I only got to fire one group after adjusting the scope, four of the bullets went into one hole, then there was a flyer about 3/8" off to the left. I've thought through the modification and see how I'd have to do it. It should go pretty smoothly unless there's something about the metal used to make the trigger that may give me problems. - If it's hardened and difficult to drill and tap, for example. Only one way to find out, I'll be sure to take pictures as I go.

	I discovered a problem with my idea, associated with my powers of observation. - What I did not notice is that the hole I was looking at is of an oval shape, not round. It is this way so that the trigger pull adjustment screw can travel into the hole at an angle that increases as the trigger swings on its pivot. It looks round on a casual inspection, but when I took a closer look I discovered that it is oval, and why. A second method occurred to me, but it will require taking the gun completely apart as a hole must be drilled and tapped in the trigger housing, from the curved rear surface. (You need to *Login* or *Register* to view media files and links) A hole drilled and tapped from the rear of the housing where indicated would (with a set screw) provide a variable stop that could only be adjusted with the stock removed. As the trigger pivots, it eventually contacts the rear of the trigger housing. A set screw poking out where the contact occurs would be able to eliminate almost all of the over-travel. Now I'll have to decide it it's worth the effort, to me. - And I'll keep trying to work out something more suitable, that hasn't occurred to me yet. - I have my good days and my bad days, you never know...
