Good day CGN,
I have a Smith and Wesson Model 29-10 (6.5” barrel) with an odd behavior. It appears when the firearm heats up from use; it seems the point of impact is shifting left? I thought it shot slightly left from new, just figured I needed more practice to correct a poor grip or trigger finger. Though now I have noticed it is becoming more pronounced, as it gets hot from usage a left bias starts to occur. This can be replicated using a 240g Campro and charges anywhere between 8.3g Unique or 18.5g of 2400 (nothing lighter/hotter).
Anecdotally this has been compared by using a rest and by having others try the revolver (with rest or free standing). It appears that when the revolver heats up, the rear sights will need to be adjusted right to compensate.
If I let it cool right down, it shoots back to or very near original point of impact (if I haven’t changed the rear sights). It seems to max out the left bias (after it gets hot) by a couple of inches at 25 yards and at least 12+” at 100+ yards, with elevation seemingly not affected.
To my layman eye - the firearm appears to be normal otherwise with no evidence of a canted barrel or fitment/seam gaps some S&Ws have experienced. All screws are tight, front sight looks tight/square and the cylinder seems to positively lock into the frame. It feels mechanically smooth and reactive when shooting single or double action. Has anyone ever experienced something similar with their Model 29 of any vintage, or have heard of this issue with any handgun in general?
I’m more curious really, as I will send it to an S&W Gunsmith if my next outing proves similar. I Plan on taking photos of the frame/barrel/cylinder fitment when hot vs. cold to compare further.
Thank you for taking the time to read my post!
Kindest regards,
