These can be somewhat of a fun thing to say the least. I just finished repairing 3 S&W mals 78G that the 'O' rings had gone bad in. One I bought new some years back, ther other two were throw away gifts because they didn't work. Now all three work, and I bought a new SIG 250 because I have the real thing and I can practice in the shop in this bad weather. Just what works for me.
