Yes, that's exactly what I mean. You can trim off a turn or two with a pair of sharp wire cutters. This will ease the spring tension for the lower powered target velocity ammo. Brownells and some of the other parts places like Numerich Gun Parts have the recoil spring assys for sale. By having two spring sets you can substitue in the correct tension for the ammo you plan to shoot. Don't go crazy clipping off coils, just take off one or a half of one at a time until you achieve the results you are looking for with your pistol. I wouldn't go beyond removing three coils unless I was getting positive results but just not quite there yet. Then, one more turn would probably be my max limit.
Its good that your getting acceptable results from the lower cost ammo. I tried that Remington ammo before but I was having detonation reliability problems even though the ammo was accurate enough for bullseye shooting. Remember it is high velocity ammo so once you start cutting coils these rounds shouldn't be shot through your gun until you acquire a high powered spring assy.
You should see a significant jump on your overall performance once you install a red dot sight.
