A good friend of mine who has a G23 and has asked me about this load from Buffalo Bore but I have never seen or heard of it till last night. Does anyone here have any first hand info?

They are standard pressure and at the top of the velocity for that range and weight projectile! They seem to have tested them in the G-23;
962 fps -- Glock model 23, Gen. 2, 4 inch barrel
969 fps -- Glock model 23, Gen. 4, 4 inch barrel
He should be good to go, but he should also beware of leading of the bore and inspect for build up. He will also need to look at the end of the chamber cut to see if any lead is being shaved and rolled up there. If that happens it can cause poor lockup and possible out of battery condition, or increase lack of support.
Thanks for the info
My advice to him was sell the 23 and buy a 10 mm :)
Anytime the cast bullets are used the advise from above needs to be remembered regardless of which semiauto pistol is used.
Revolvers setup with semiauto cartridges that have the end of chamber cut as opposed to a tapered cut chamber with moon clips can also see issues.
