Where did your Bobcat wear out?
I have a couple in .25 and they seem to be doing fine. I've lost track of fired rounds but I'll guess about 750 for one and 1500 the other.
Have a Jetfire with about 1k-1500 on it and it, too, looks fine.
I did replace recoil springs on the higher count Bobcat just because I got it used. They were about 15% shorter than the new ones.
