Not to get off topic, your stock is likely cracked because of a shattered recoil buffer. If you are patient these parts can be had from midwayusa (to include a factory replacement stock) at a very affordable price. I had to do the same with my camp 9. Also a derlin buffer can be found at wisnersinc. These buffers should hold up for a longer period of time. Make sure to check your bolt recoil spring, if this is weak it will cause the bolt to recoil excessively and shatter the buffer. I learned this to with my camp 9 . As for price I got mine for 350.00 some time back. Hope this helps
