Way back in the last century, I found that the barrel weights were more effective when shooting 50yd slow fire vs. 25yd timed or rapid fire. The weight seemed to minimize and/or slow down the muzzle movement (horizontal figure-8). I used the weights on my Model 52 as well as on my HighStandard Military Trophy. A model 41 has replaced the HS and I leave the light barrel weight in the 7 3/8" barrel for slow fire and switch to the shorter barrel for timed and rapid.
In my advanced age, the weight only makes the guns heavier.
