I have this inforce APL on a G19 and I'm considering buying a JM custom Kydex holster so I can carry the G19 with a light.  I have had to send this light back to Inforce to be replaced before and occasionally I've had battery drain issues with the inforce.  Has anyone else had issues with their Inforce apl?  I guess my question is, should I just buy a surefire X-300 for the G19 instead of running the Inforce.  I do really like the way the inforce light paddles work however.

Which Generation APL?

I'm not even certain about that.  possibly Gen 2.

I have both the apl and x300 and both have failed me and both have had excellent cs and made it right. I love both however my olight on my 19 has never failed me and I trust it to come on when I need it and never have to buy batteries.
