So your nozzle still breaks regardless?

Even if you go with "Something softer" it will still break. It all depends on how fast your slide can recoil and how stiff that nozzle return spring is. you have to keep in mind that the loading muzzle stays stationary until the spring kicks in. At which time, it actuates the nozzle to return. You can see the action when you charge your gun. Often times, you'll see the muzzle not move in the initial stages of the slide pull. Then as you pull it even further to the rear, the loading muzzle will snap backwards. This is because there is no longer any travel for the nub. That is, the nub has travelled far enough into the BBU rails that it no longer has anywhere else to go while the slide is still charging rearwards.
So if there isn't enough power to spring to resist the recoiling slide, the nub will slam against the the plunger. AND if the plunger is too long, the force of the recoiling slide will shear the nub right off...
Your worry of the spring crimping is valid. However, there are many BBUs that don't accomodate a plunger for that spring and they still stay relatively undamaged during operation. THe Glock 17 for example doesn't have a plunger. Nor do the hi-capa nozzles and they stay uncrimped for a long while (at least in my guns). But in general terms, most GBB pistols crimp that spring regardless of how much caution each operator exercises. It's common. This is why there aftermarket companies that carry replacement loading muzzle springs in their brand line up.
You have to cut it to the right length. As long as you don't cut it too short that the plunger's function becomes non-existent, you're ok. That is, don't cut it too close to the "base" or the fat part where the spring rests against...
All loading muzzles eventually break in any GBB pistol (or even GBBRs). This is just the nature of the loading muzzle. Sometimes they even break in areas that you think is the sturdiest. For example, the loading arm might break or the actual air output part of the muzzle where it is the thickest may crack or even the body of the loading can fall apart under heavy pressure.
On the Glock 18c, the nub is the most common area of breakage because of that plunger....
