Anyone use one of the "Gas Pedal" slide stops? Any reliability issues with them?

Will they work with a Safariland holster?

I bought my son one for Christmas. I'll let you know in a few days.

I have them on my P3220 FS, and both P320 x5's, and have had no issues at all. I shoot a lot of USPSA and SC, so they get used a bit. I have RHT and GX holsters though, not Safariland, but never noticed an issue, for what that is worth

They work great but holster compatibility might be an issue. I prefer the Armory Craft takedown lever tho.
