model 25 sight question

[mike56]

Had a ruger redhawk in 45 colt. 5 inch barrel. Had the rear sight bottomed and it still was off. Needed a higher front. Ended up selling it.

Thinking about a new 25 with the 6.5 barrel. Anyone know how those sights are regulated to the POI? Is there enough adjustment in the stock sight or will I have the same issue?

Other than the heavy triggers, I'm ok with the new classic

It may all depend on the load you are intending to use. A normal factory load should shoot to POA with adjustment left. Very hot loads or mild target loads may require some modification. I shoot a 25-2, 45acp and anything from +P to light target loads is within the range of adjustment out to 25 yards, but that isn't 45 Colt.

A S&W rear sight can have the blade changed to various different heights to adjust for longer ranges or extreme loads.

Lots of things to consider here. Some have been mentioned, but the "shooter" hasn't been and that's just as important as other considerations.

My 25-5 6", bought new forty years ago will shoot about 4" to 5" high at 25 yards with the standard cast bullet handload of the Lyman #454424 255 grain SWC and 8.5 grs. Unique, about 850 fps, perhaps the most popular of .45 Colt loads. This is with the rear sight bottomed out. But, I shoot with one hand, Bullseye style. Using a two handed hold will bring the group down noticeably. Using one hand and a very firm grip will also bring the group down, but I don't get best accuracy with a very firm grip.

All this will vary from one shooter to another, at least slightly, but shoot enough with your intended load and different shooting styles to see where your point of impact is and go from there. Swapping out rear blades may be required in some cases, but it's important to do enough shooting to find out if this is really necessary.

Of course, the much repeated information about lighter bullets shooting lower is almost always true with revolvers, but if you're not getting good accuracy with a lighter bullet, lowering the point of impact isn't worth much.

Recoil arc!

The arc the gun travels in under recoil is the key to all the problems! Light & fast bullets means the bullet is in the barrel for a shorter period of time so it exits the barrel lower in the recoil arc! Heavy bullets means more recoil and slower so the bullet is in the barrel longer. The gun is higher in the recoil arc!
The recoil arc is different for EVERY shooter. One shooter muscles the gun down and another leaves the gun rise in the arc more! This problem becomes very apparent when the yardage is stretched farther out.

The Model 25 .45 Colts I have had (all 4-inch barrels) invariably shot high for me. They could be zeroed with lighter bullets but I don't buy a .45 Colt revolver to shoot lighter-than-standard bullets. I have heard/read similar observations from others, and contrarily, others say their guns shoot just fine. I guess you won't know in your case until you buy the gun and try it.

Yep I had a Model 25-5 ,I think, 45 Colt and it shot so high with bullets in the 250 grain range as to be unusable. I passed it on to someone probably more interested in its looks. I was interested in performance with normal bullet weights. Probably a mistake but that is what I did.

If the new M25 has a .146" high rear sight leaf, substituting a .126" or .106" leaf, might provide the needed correction.

The model M-25 classic will need a taller front sight when shooting with 250 gr loads. That's what I did on mine.

 

[BLUEDOT37]

My M25-13 has factory .270" front sight & .130" rear blade and it's well regulated for 250gr or 300gr (P+) loads.
