the standard combo from crappy tire works on my gen 3, even with tact light.
I did notice that I won't be able to use the Glock case that it came in. Maybe a combo cable lock would work better, I'll have to see if I can find any of those.Every trigger lock I have bought for any of my guns works on my Glock Gen. 4 as well. It needed a new case for my combo lock because of the bulky lock and the small Glock case, but any lock should work.
The only locks that I've seen not work on Glocks, are the little $2 ones with the two little holes. Those don't even come close to working in any way I've tried, at least
Funny, I use those locks and they fit my glock 17 just fine? And I don't have to buy a new case as they're slim and work fine in the original glock case.
Besides, 12 locks for $9.99, how can you go wrong?
