http://www.gem-tech.com/store/pc/viewPrd.asp?idproduct=1137 Anybody done this or have one of the new cans? Mine is 20+ years old now and can't be taken apart like the new ones. Thinking that $250 might be worth it, and no government wait. Pros: New core with longer expected life. .22 Mag rated. Comes apart for cleaning Cons: $250----about the price of a brand new can. Has to go back to factory for undetermined time. Thoughts?? Thanks.
