The lock out method works just fine. The only twisty I ever really carried was the Jetbeam AA light. Jet something, I always get them mixed up. It came on more than a few times loose in my pocket and just a few times clipped on my pocket. Not that big of a deal really. I noticed it before it was able to drain the cell down too terribly. Then I started carrying mostly tail clicky lights and now I’m back to carrying mostly side switch lights. Nicely recessed switches so I have never had one of those come on. I have had a Tip and a Tini that come on way too easy in my pocket on a keychain. Love them both, but they are always dead.
