I bet the Olight PL-Mini 2 would fit on there just fine, but getting someone to make a holster for you can be a challenge.
I ditched my original TLR-7 for a PL-Mini 2 on my P-07 because I didn't like the TLR-7 side switches... didn't like using them, and didn't like that they were prone to be pressed accidentally by the inside of a holster. Now that the models with the new switches are out, I have considered switching back to Streamlight, but the Olight hasn't failed me yet, and I have holsters made so I'm good for now.
