Let's try again.
Here's my try and loading the Lee 358-125-FN over a minimal load of Titegroup. It gives a very satisfying KERPLUNK going into the chamber of the P1.
Ah! Hah! I finally got the picture to load!!!
That picture and your description is a good illustration of why you get varying reports about this bullet's suitability in 9mm.
Bullets from my mold loaded to that same length will not "plunk" into even a relatively loose Glock chamber; mine must cast larger than yours. Because of the larger diameter, they have to be seated deeper, even though they're sized correctly.
It's a decent bullet for light loads, if it fits. If you get one from Lee that casts a little large, it may give you trouble in 9mm but will still work fine in 38/357.
