The TCP is a great little gun, as long as you don't need to rely on it. Mine went back to Taurus twice, and was still unreliable. Traded it and got the LCP. LCP is well worth the extra $100.
And, success! Happy owner of a brand - new, no-lock model 642 Smith! Went back to my revolver roots and couldn't be happier! Thanks for the input, folks!
